Fixed in 22489bf559ab8fae335adf5cda39c5873062afe9

Looks like it was caused by incorrectly handling recycled URBs which are partially received (ie we get the complete but not the submit at the beginning of the capture). Linux based captures should have primarily been affected although Windows possibly was as well.

Please let me know if you still have issues!
