Hi, I've got a small problem with a nice little thing called "USB Memorybird" (Fujitsu-Siemens) ... It is bascially a 64 MB Flash chip in a small plastic pen that you can carry with your keys. It doesn't need any battery and you can plug it directly into a USB socket. Very neat. Works without any drivers on WinME and Win2k, so I assume it should be some standard USB mass storage device. FreeBSD 4.5 recognizes it out of the box and attaches it as a SCSI disk, but I cannot access it. This is what happens: From the boot log: uhci0: <VIA 83C572 USB controller> port 0xd400-0xd41f irq 10 at device 7.2 on pci0 usb0: <VIA 83C572 USB controller> on uhci0 usb0: USB revision 1.0 uhub0: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered This appears when I connect the Memorybird: umass0: Fujitsu Memorybird, rev 1.00/1.00, addr 2 da2 at umass-sim0 bus 0 target 0 lun 0 da2: <Fujitsu Memorybird 1.04> Removable Direct Access SCSI-0 device da2: 650KB/s transfers da2: 62MB (128000 512 byte sectors: 64H 32S/T 62C) This is the output from "usbdevs -v" (note that there is a ~10 seconds delay!): Controller /dev/usb0: addr 1: self powered, config 1, UHCI root hub(0x0000), VIA(0x0000), rev 0x0100 port 1 powered < ~10 seconds delay > port 2 addr 2: power 100 mA, config 1, product 0x0100(0x0100), vendor 0x0d7d(0x0d7d), rev 0x0100 When I type "fdisk da2", it hangs for a while, then prints: fdisk: can't open device /dev/da2 fdisk: cannot open disk /dev/da2: Input/output error At the same time, the kernel logs this: Feb 7 20:00:31 lurza /kernel: umass0: BBB reset failed, TIMEOUT Feb 7 20:00:36 lurza /kernel: umass0: BBB bulk-in clear stall failed, TIMEOUT Feb 7 20:00:41 lurza /kernel: umass0: BBB bulk-out clear stall failed, TIMEOUT Feb 7 20:00:51 lurza /kernel: umass0: BBB reset failed, TIMEOUT Feb 7 20:00:56 lurza /kernel: umass0: BBB bulk-in clear stall failed, TIMEOUT Feb 7 20:01:01 lurza /kernel: umass0: BBB bulk-out clear stall failed, TIMEOUT The same happens when I try to dd some block from the device to /dev/null. During my experiments I also got these messages (I don't know if they're important): Feb 7 19:54:46 lurza /kernel: da2: reading primary partition table: error reading fsbn 0 Feb 7 19:54:56 lurza /kernel: umass0: BBB reset failed, TIMEOUT Feb 7 19:55:01 lurza /kernel: umass0: BBB bulk-in clear stall failed, TIMEOUT Feb 7 19:55:06 lurza /kernel: umass0: BBB bulk-out clear stall failed, TIMEOUT Feb 7 19:55:06 lurza /kernel: (da2:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0 Is there a chance to get this to run? Clearly the umass driver recognizes it and attaches it as a SCSI disk, so I assume that it can't be _that_ hard to convince it to work with FreeBSD. :) Are there any quirks that I should try? I'm not extremely familiar with that kind of stuff, but I'm willing to experiment. Thanks in advance for any help! I would _really_ love to get this thing working.
