Hello, I've got this 'big' problem for the hotplug feature:
I'm trying to plug/unplug the midisport1x1 from M-Audio. The plug works like a charm,
hotplug does its job, load the firmware (fxload) and snd-usb-audio, if not inserted,
is auto-loaded. But <hen I unplug the device, and I want to plug it again, the usb
just hang, trying to rmmoding snd-usb-audio or anything else usb related will just
hang.
I've disabled alsa in the kernel, installed instead alsa-driver-1.0.3rc2, and
confiured it with intel8x0 (I'm on a dell inspiron 8200 laptop)
, usb-audio and sequencer.
My kernel is a 2.6.3rc4, I'm using debian unstable.
the hid and uhci-hcd are modules, and autoloaded at boot via the "uhci-hcd" line in
/etc/modules
I've cleaned anything snd- related in the modules.conf and so far that works.
### dmesg gives ###
usb 2-1: USB disconnect, address 2
usb 2-1: new full speed USB device using address 3

* now let's unplug it *

I've tryed to comment out, and do some silly modifications in this file, but doesn't
have any effect.
So I'm wondering if I'll see one day the hotpug for my new midi device wworking ... :/
If you guys have a solution, well... that'll be a good relief :)
Cheers,
Mathieu
PS: maybe an lsusb -v could as well help...

Something strange I just notice is, even if the device is inplugged (after rmmoding
and bugging all usb) I can do:
$> sudo umount /proc/bus/usb
$> lsusb
$> sudo mount /proc/bus/usb
$> lsusb

ok the usbfs is probably totally dead and shows the last working state... hey but my
mouse is still working fine (in condition I don't unplug and replug it ^^ )
