USB device stopped working - can't set config #1, error -71

[Rene Rebe <rene@exactcode.de>]

Hi all,

with the latest kernels (definetly 2.6.17 and 1.6.8-rc*, I do now know off 
hand when this started) I can not access some (I think all USB 1) scanners 
via my SANE/Avision backend:

usb 3-1: new full speed USB device using uhci_hcd and address 2
usb 3-1: configuration #1 chosen from 1 choice
usb 3-1: can't set config #1, error -71

write(2, "attach: opening libusb:003:002\n", 31) = 31
open("/proc/bus/usb/003/002", O_RDWR)   = 4
ioctl(4, USBDEVFS_SETCONFIGURATION, 0xbfc10c74) = -1 EPROTO (Protocol error)
close(4)                                = 0
fstat64(2, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 1), ...}) = 0
write(2, "[avision] ", 10)              = 10
write(2, "attach: open failed (Invalid arg"..., 39) = 39

Currently this is on an x86 Apple MacBook:

Bus 005 Device 002: ID 05ac:1000 Apple Computer
Bus 005 Device 001: ID 0000:0000 Virtual Hub
Bus 004 Device 002: ID 05ac:8240 Apple Computer
Bus 004 Device 001: ID 0000:0000 Virtual Hub
Bus 003 Device 001: ID 0000:0000 Virtual Hub
Bus 002 Device 002: ID 05ac:0218 Apple Computer
Bus 002 Device 001: ID 0000:0000 Virtual Hub
Bus 001 Device 009: ID 05ac:020c Apple Computer
Bus 001 Device 008: ID 046d:c00c Logitech Inc. Optical Wheel Mouse
Bus 001 Device 007: ID 05ac:1003 Apple Computer
Bus 001 Device 004: ID 05ac:8300 Apple Computer
Bus 001 Device 002: ID 05e3:0606 Genesys Logic, Inc.
Bus 001 Device 001: ID 0000:0000 Virtual Hub

While this simple lsusb is enough to trigger the issue:

usb 3-1: new full speed USB device using uhci_hcd and address 3
usb 3-1: configuration #1 chosen from 1 choice
usb 3-1: can't set config #1, error -71

And the affected devices do not appear in the lsusb output.

Btw: I saw a patch related to usb1 devics behind usb2 hubs, but
I think it made no difference here.

Btw2: I also do not see the standard bluetooth USB HCI that is suppost to be 
in the MacBook and that is listed and works fine in OS X.

Yours,
