>Description:
Transcend JetFlash120 memory stick (perhaps, others as well) isn;t detected; system just gives an IOERROR:
ehci_pcd: change=0x00
uhub_explore: status change hub=1 port=8
ehci after reset, status=0x00001005
ehci port 8 reset, status = 0x00001005
usbd_new_device bus=0xffffff0000a1b000 port=8 depth=1 speed=3
usbd_new_device: addr=2, getting first desc failed
usbd_remove_device: 0xffffff0016b47d00
ehci_device_ctrl_close: pipe=0xffffff001784a180
ehci_intr1: door bell
uhub_explore: usb_new_device failed, error=IOERROR
uhub1: device problem (IOERROR), disabling port 8
(This is -CURRENT, with USB debugging enabled and "options DIAGNOSTIC")
>How-To-Repeat:
Try to use it :-)
>Fix:
Probably, this is a hack but it works here: re-get desc; with this patch a relevant part of dmesg:
umass0: <Generic Mass Storage Device, class 0/0, rev 2.00/1.41, addr 2> on uhub1
umass0: SCSI over Bulk-Only; quirks = 0x0000
umass0: Get Max Lun not supported (STALLED)
umass0:7:0:-1: Attached to scbus7
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <JetFlash TS1GJF2A/120 8.07> Removable Direct Access SCSI-2 device
da0: 40.000MB/s transfers
da0: 980MB (2007040 512 byte sectors: 64H 32S/T 980C)
