Hi,

it looks like you use not hi-speed (usb2.0) controller.
If it work in full speed then you can get only ~10 Mbit/sec.
with 320x240 it should be low frame rate or try 160x120.

please send dmesg from you arm system.

Enable debug for uvcvideo module:

sudo echo 0xfff > /sys/module/uvcvideo/parameters/trace

reproduce the problem
attach dmesg to email

dmesg > dmesg

PS: Please do not use HTML formatet mails.
