[2.5.52][USB] USB Device unusable

* NOTE: This is -mm2. I will be compiling 2.5.53 (-mm1) today and test this as well.

Initial Power on of USB Device:

Please let us know how 2.5.53 works, as there were a number of ehci patches in it that might have helped.

thanks,

2.5.53-mm1 compiled w/ lm_sensors merged in:

Same error however new thing:

When a non-root user tries to configure the USB device the userland program returns 'Unable to claim USB device'

When a root user tries to it reports the same errors as in the previous email.

Shawn.

With 2.5.52/2.5.53 (mm2 and mm1). I notice that my network connectivity drops. I loose connectivity to the outside. This just started to happen while trying to configure the USB device (in this case a cheap digital camera).

Odd.

Shawn.

So you are using usbfs? What program? Nothing changed with usbfs from 2.5.52 to 2.5.53, but some things did change from 2.5.50 to 2.5.51. Did .50 work for you?

thanks,

greg k-h

mount reports:
usbfs on /proc/bus/usb type usbfs (rw)

/etc/fstab:
usbfs /proc/bus/usb usbfs defaults 0 0

well, KDE has a plugin that utilizes libusb, libgphoto2 to manipulate the camera.

I never tried the USB on this machine in 2.5 or 2.4.

Shawn.

And you are sure that this camera works with Linux?

Have you tried this camera on any other Linux machine, with any other kernel?

thanks,

greg k-h

Well, libgphoto2 reports that my camera is supported. It supports JamCam versions 2.0 and 3.0.

I haven't tried it in any other Linux machine.

Shawn.

As there are no visible usb subsystem errors or failures here, I would take it up with the gphoto people :)

Good luck,
