This is almost exclusively caused by a bug in device firmware. > Resetting the USB device using libusb also does not solve the > problem. It is not possible to reset a USB device from software. The closest you can come is to manipulate the hub which the device is connected to and make it tepmorarily remove power from the right port, but there is no API for doing this. IIRC the thread on the libusb list ended with the discovery that the device firmware could not handle a configuration request when it was already configured, but please do check the archive. I believe it was discussed in the last three or four months. //Peter _______________________________________________ libhid-discuss mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/libhid-discuss http://libhid.alioth.debian.org/
