Hello list,

I had my HP P1005 printer working just fine under 7.2-RELEASE, but I
just updated to 8.0-RC2 and the driver doesn't seem to like the new
USB stack.

I was using the foo2xqx driver [ http://foo2xqx.rkkda.com/ ] -- with
this driver, the firmware needs to be sent to the printer each time it
is turned on, like this: cat sihpP1005.dl > /dev/ugen0.0.

Now, according to dmesg, the printer is now known as device
/dev/ugen2.2, but I can't send the firmware to it (and I can't send
the firmware to any other ugen* device either):

cat sihpP1005.dl > /dev/ugen2.2
cat: stdout: Input/output error

(Trying the same as root or with sudo doesn't make any difference.)

My /etc/devfs.rules:

add path 'da*' mode 0660 group operator
add path 'usb' mode 0777
add path 'usb/*' mode 0666
add path 'usbctl' mode 0666
add path 'ugen*' mode 0777

ls -lh /dev/ugen* with the printer connected and turned on:

lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen0.1 -> usb/0.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen1.1 -> usb/1.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen2.1 -> usb/2.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 20:31 /dev/ugen2.2 -> usb/2.2.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen3.1 -> usb/3.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen4.1 -> usb/4.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen5.1 -> usb/5.1.0
lrwxrwxrwx  1 root  wheel     9B Oct 31 17:18 /dev/ugen6.1 -> usb/6.1.0

Googling around for possible solutions didn't turn up anything
successful for me.  I asked on the FreeBSD Forums and was told to turn
on debug informations on ugen by sysctl hw.usb.ugen.debug=1 -- I did,
but I don't see anything new in dmesg or /var/log/messages -- maybe I
don't know where to look?

Anyway, any suggestions?

How did you update?

Did you recompile foo2xqx ?

You need to specify the endpoint. ugenX.0 is the control endpoint.

I've tried each combination of bios settings, and the problem
persists. It's strange -- the first suspend/resume cycle works great,
everything comes back on, USB ports still active, etc...

It's the subsequent suspend/resume cycles where I see the problem.
I've attached my dmesg output, in case it matters.

 I've tried each combination of bios settings, and the problem
 persists. It's strange -- the first suspend/resume cycle works great,
 everything comes back on, USB ports still active, etc...
 
 It's the subsequent suspend/resume cycles where I see the problem.
 I've attached my dmesg output, in case it matters.

A small update. I tried this gadget with FreeBSD 8.0-rc2.
Without uchcom loaded it prints this in /var/log/messages:
Nov  1 21:25:33 kg-t2 root: Unknown USB device: vendor 0x4348 product 0x5523 bus uhub0
Nov  1 21:25:33 kg-t2 kernel: ugen0.2: <vendor 0x4348> at usbus0

If I insert the gadget after loading the uchcom driver, the machine panics. The same happens if I load the driver with the gadget inserted. No core dump.

I've trie this on two different machines, one running the i386 and the other the amd64 version of FreeBSD 8.0-RC2.
Both panics with the uchcom driver and this gadget.

Hi,

Try to fetch:=20

/sys/dev/usb/serial/uchcom.c=20

=46rom FreeBSD 9-current and rebuild the uchcom module or kernel.

Known issue I think.

Awaiting at least 8.0-RELEASE (but preferrable 8.1-RELEASE - "dot zero" still 
will buggy). But this is good news. Probably, my Genius Optical Value and 
Microsoft 5000 twins will work :-)

>Description:
This happens after reboot. All the labels on the external USB 450GB HDD, which is gjournaled, are erased.  This drive I know works fine and am pretty sure it's a software issue.  I thought this was a fluke, but I'm reporting this bug after it happened for the 2nd time.  I've been able to recover the data by relabeling the disk w/ the same sizes.
>How-To-Repeat:
Reboot
>Fix:
If you know the exact label sizes, just renter and untoggle newfs.

Hi,

Thanks for your patch.

What is the correct "sc->sc_offs" value? The sc_offs field is used by more 
than reset, and should be set correctly. I.E. The right solution is not to 
remove the ehci_reset() call.

[...]

The sc->sc_offs value is initialized early during ehci_init().  Afterwards a
ehci_reset() is ok, but before it is not good.

[freebsd-current cc'd, as that was where the thread started, but this
probably belongs on -usb, replies should go there]

Hmm, this looks like a serious bug, possibly in the new USB subsystem
(HPS CC'd).

I've got an axe(4) device, which also does the same:

ugen7.3: <vendor 0x0b95> at usbus7
axe0: <vendor 0x0b95 product 0x7720, rev 2.00/0.01, addr 3> on usbus7

ukphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
ue0: <USB Ethernet> on axe0
ue0: Ethernet address: 00:50:b6:05:57:a7
ue0: link state changed to DOWN

Hi!

In umass_attach() the sc->sc_mtx will be initialized.  This mutex will be

destroyed in umass_detach() right after the last unlock.

Fair enough, but this must be mentioned in src/UPDATING.

I recently had a partition table wiped out on a non-boot disk, an 8 GB  
flash drive on a SATA port. I don't know that I can reproduce it, but  
if there are more similar reports it might be worth looking in the  
disk subsystem rather than USB.

I noticed that the latest uchcom.c had been MFC'ed to RELENG_8, so I
fetched and built that instead.
root@kg-t2# uname -a
FreeBSD kg-t2.kg4.no 8.0-RC2 FreeBSD 8.0-RC2 #0: Tue Nov  3 20:13:10 CET 2009     root@kg-t2.kg4.no:/usr/obj/usr/src/sys/GENERIC  i386

And in /var/log/messages I see:

Nov  3 22:17:43 kg-t2 kernel: ucom0: CH340 detected
and usbconfig shows:
root@kg-t2# usbconfig list

ugen0.2: <USB-SER! vendor 0x4348> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

But where is ucom0?

FreeBSD kraken 8.0-RC2 FreeBSD 8.0-RC2 #0: Sat Oct 31 05:40:55 EST 2009     robj@kraken:/usr/obj/usr/src/sys/KRAKEN  i386
>Description:
Thankyou for porting libusb-1.0 to the FreeBSD kernel. Being new to usb programming, I tried to compile the non-trivial example program, dpfp.c,  provided with the libusb-1.0.3.tar.bz2 tarball available from "http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.3/libusb-1.0.3.tar.bz2/download" . I found two problems

1. FreeBSD libusb10 is not quite portable. Here is a diff required to get dpfp.c to compile:
[robj examples]diff dpfp.c dpfp.c.orig 
30,32c30
< #include <libusb.h>
< 
< #define LIBUSB_CONTROL_SETUP_SIZE (sizeof(struct libusb_control_setup))
---
> #include <libusb/libusb.h>
62c60
< static libusb_device_handle *devh = NULL;
---
> static struct libusb_device_handle *devh = NULL;


2. Some libusb-1.0 functions are not implemented. Here is an attempt to link dpfp.c:
[robj examples]gcc -O0 -g -o dpfp -lusb dpfp.c 
/var/tmp//ccPc8n2t.o(.text+0x4dc): In function `set_mode_async':
/home/robj/TMP/libusb-1.0.3/examples/dpfp.c:182: undefined reference to `libusb_fill_control_setup'

Ah! I did know that, but had forgotten and that "ucom0:" in the output
confused me. Thanks!

Here is an idea: could we have the class of devices (usb devices that
create / use ttys) report which tty they are using when they attach?
Ie, instead of
ucom0: CH340 detected

We could have:
ucom0: CH340  detected, using /dev/cuaU0
or something like that?
I don't care if it is the driver, ther kenel or another part of FreeBSd
that outpus this information, I just want it t be presented to the user.

Just my 0.02 eurocents.

Hello!

First of all, excuse my English.

Well, i have an AnyDATA ADU-500A Rev.A USB-modem, and i'm going to use
it for my handmade "VIA EPIA-based mobile router". I have installed
latest 8.0-RC2 and configured ppp, and now everything works just fine,
except that I got a lot of such messages on console when I run ppp:

ubsa_cfg_request:371: device request failed, err=USB_ERROR_STALLED (ignored)

I really want to work it out, and I have some spare time for experiments,
but haven't any experience of debuging kernel drivers. Can anybody give me
a clue to solve this little problem?

Did you look in the source code:

   Unfortunately, I do not have access to this adapter anymore. Unless  
there are other people with a similar need, this PR could be marked  
for expiration (say 2 months without a follow up).

FreeBSD kraken 8.0-RC2 FreeBSD 8.0-RC2 #0: Fri Nov  6 02:43:24 EST 2009     root@kraken:/usr/obj/usr/src/sys/KRAKEN  i386
>Description:
I was getting some weird values for usb configuration descriptor extra length. Valgrind is a wonderful tool recently ported to FreeBSD by stas@FreeBSD.org. Using valgrind I found the following problems (fixed in the attached patch):

1. In libusb10_desc.c, libusb_get_config_descriptor(), at line 162:
	pconfd->interface = (libusb_interface *) (pconfd +
	    sizeof(libusb_config_descriptor));
should be:
	pconfd->interface = (libusb_interface *) (pconfd + 1);
This problem causes illegal writes past the end of pconfd.

2. In libusb20_ugen20.c , ugen20_get_config_desc_full(), cdesc and ptr are not initialised. This problem causes branches on uninitialised values.

3. In libusb20.c, libusb20_be_free(), pbe is not free'd. This problem causes a minor memory leak.


>How-To-Repeat:
Compile the following test, link with a debug version of libusb.a and run valgrind.

#include <libusb.h>
int main(void) {
  libusb_context *context;
  struct libusb_device **devs;
  struct libusb_config_descriptor *config;

  libusb_init(&context);
  libusb_get_device_list(context, &devs);
  libusb_get_active_config_descriptor(devs[0], &config);
  libusb_free_config_descriptor(config);
  libusb_free_device_list(devs, 1);
  libusb_exit(context);
  return 0;
}

>Fix:
Apply the attached patch in /usr/src/lib/libusb

 Hi,
 
 Regarding my bug report usb/140325: Missing/incorrect initialisation and memory leak in libusb10/libusb20. I revised my simple test to:
 
 #include <stdio.h>
 #include <libusb.h>
 
 int
 main(void)
 {
   libusb_context *context;
   struct libusb_device **devs;
   libusb_device_handle *handle;
   struct libusb_config_descriptor *config;
   struct libusb_device_descriptor device_desc;
   int bytes;
 #define STRLEN 128
   unsigned char str[STRLEN];
   int transferred;
   
   libusb_init(&context);
   libusb_get_device_list(context, &devs);
   libusb_get_active_config_descriptor(devs[0], &config);
   libusb_free_config_descriptor(config);
   libusb_get_device_descriptor(devs[0], &device_desc);
   libusb_open(devs[0], &handle);
   libusb_get_string_descriptor_ascii(handle,device_desc.iProduct,str,STRLEN);
   libusb_claim_interface(handle, 1);
   libusb_bulk_transfer(handle, 1, str, STRLEN, &transferred, 0);
   libusb_release_interface(handle, 1);
   libusb_close(handle);
   libusb_free_device_list(devs, 1);
   libusb_exit(context);
 
   return 0;
 }
 
 and found two additional problems:
 
 4. A jump on uninitialised occurs at libusb20.c:658 in libusb20_dev_req_string_sync():
   req.wLength = *(uint8_t *)ptr;	/* bytes */
   if (req.wLength > len) {
 To fix, zero the upper byte with:
   memset(ptr, 0, len);
 
 5. A memory leak occurs for devs[0] in the above test. devs[0]->refcnt is incremented to 3 during libusb_bulk_transfer() but not decremented on exit from that function. Consequently, devs[0] is not freed in libusb_free_device_list(). I couldn't see a quick fix for this and it's a minor memory leak (44 bytes) so I will leave it for an expert.
 
 Regards,
 
 Rob

Hello, Hans!

 HPS> Did you look in the source code:
 HPS> /sys/dev/usb/serial/ubsa.c

Yes, of course! Line #317 belongs to ubsa_cfg_request(), which just calls
another function, ucom_cfg_do_request(), with some parameters. But this
function is called several times in the code, so I've changed code of
ubsa_cfg_request() function to see, which config requests are failed:

DPRINTFN(0, "device request failed, err=%s, index=%d, value=%d "...

I have got a lot of messages like this one:

ubsa_cfg_request:371: device request failed, err=USB_ERROR_STALLED,
index=10, value=1 (ignored)

where index/value pairs sequence is:

10/1, 11/1, 12/0, 0/24, 3/0, 2/3, 1/0, 16/384, 0/2, 3/0 and so forth.

It seems, that driver tried to set some config parameters like DTR, RTS,
BAUDRATE etc, and failed. But after all, modem is working (maybe, with
non-optimal settings or default settings).

So, I need an advice: what can I do to find the cause of failed config
requests?

Hello, Hans!
On November, 06 2009 at 11:29 you wrote to Alexey Markov:

 HPS> Maybe you device belongs in the ugensa.c driver and not ubsa.c

No, AnyDATA ADU-500A definitely belongs to the ubsa driver, it even
stated in the man page of ubsa. Just in case i had tried the ugensa
driver, but it doesn't work at all.

 HPS> if it does not support all those DTR/RTS ... settings?

I think, it may be connected with this PR: usb/134950

 HPS>  Do you have a datasheet for the modem in question?

Alas! There is no any datasheets neither in Google nor on manufacturer
site. :-(
