I would gess that this is caused by the high data amount of both devices. The Data is to much for one single USB-Bus (not ports). Try to check which bus the devices are connectet to by $lsusb . Then simply try to connect the devices to different buses. Another idea would be that the webcam is claiming the hole bandwith of to USB-port. Webcams request a whole load of bandwidth, usually more than they need. $sudo rmmod uvcvideo
$sudo modprobe uvcvideo quirks=128  This will be reset every reboot. If this works, create the following file: $sudo vi /etc/modprobe.d/uvcvideo.conf


containing the line:

options uvcvideo quirks=128

Then simply try to connect the devices to different buses. Another idea would be that the webcam is claiming the hole bandwith of to USB-port. Webcams request a whole load of bandwidth, usually more than they need. The uvcvideo kernel module can be set to ignore the requested bandwidth, and to calculate the right bandwidth.
