What kind of "out of memory errors"? dmesg? How many memory do you have on your device? Currently stk1160 dallocate memory for usb transfer buffers on every stop and has to reallocate on every start. This approach is not very smart, as fragments memory without reason. You can take a look at a similar problem on em28xx driver and a patch proposed: http://patchwork.linuxtv.org/patch/9875/ I'm not telling you this is your problem, but could be.

I guess I could start a github repo to host a 3.0.8 tree with the stk1160 driver if that helps you.
