I use a tool called hidmon to control the parameters of my LCD in shell

to RAM. I just got this error message:
hid_force_open failed with return code 13
The kernel log contains lines like this:
usb 1-1.3: usbfs: USBDEVFS_CONTROL failed cmd hidmon rqt 129 rq 6 len 9 ret -110
Unplugging and replugging the USB cable of the LCD didn't work.
However, after a further suspend/resume cycle it works.
This is Linux 2.6.25-rc5. The behaviour is not repoducible, though.
However, I just mention it for the case that this might ring a bell
somewhere.
This in fact looks like a problem with usbdevfs and/or libusb library, not
the in-kernel HID drvier.
Did this work before? In 2.6.24? 2.6.23? Alan (added to CC, as well as USB
It worked in 2.6.24 and several 2.6.25-rc kernels, including the
currently running 2.6.25-rc5.
Please don't drop people and mailinglists from CC. It makes it hard to
find your posts, if you do so.
I have restored it.
