USB_ST_URB_PENDING (bad). My guess is that after urb_priv->state is
set to URB_DEL there must be a guarenteed way to get dl_del_urb() called.
However I can see it.
Hints would be appreciated.

This prevented the timeout from occuring for the first urb to be unlinked,
but not the second. :-(
Any more thoughts would be

Had a chance to attach the drive to a Windows system this
weekend, and had the same results, which seemed to indicate
that the drive may be bad. Took it in and exchanged it for
a new one, which has worked flawlessly for over 6 hours now,
so I think this issue has been resolved. Thanks to those

Instead of making another USB-specific file system, why
Hi...
Looking at the Linux USB code (2.4.3) and I wonder why I dont have to acquire
any locks to access the usb_device structs.
When the device is disconnected in usb_disconnect() the usb_device struct is
freed, but no one prevents code that already has a pointer to it to access
it. And usb_h

On many systems USB is an internal IRQ route, not configurable through PIRQ
at all, despite what the PIRQ table tells you.
Just a possibility.

BTW a nice way to write user space drivers with a special file interface in
/dev is to use FUSD:

This can probably be done by having write() return as in the O_NONBLOCK
case when it detects out-of-paper, and by having usblp_poll() mark the
file desc
I've compiled the usb_skeleton.c module and loaded this module.
I've managed to open a USB-device, but that's it.
How can I write a application that uses this module?
Can I only use the file-operations like (owner, read, write, open and
release)?
Is there a way to set the baudrate, get the vendor/
ct with this device? Anybody have an example in
C?
Is it good to use echo or stty in console to do a quick test if I can
read/write?
Thanks

Yes, noted the original, but was out tonight. Congratulations and good work!!!
I wish I had a phillips cam to test it out on... I'll have to check which

when plugged in but a cat of js0 showed no activity. However if I used:
usbmodules --device /proc/bus/usb/xxx/yyy
it started working (thanks to Andrew Fuller for the fix).
