pbio/drv/usb: Increase transmit timeout.

When USB is receiving and transmitting a lot at the same time, transmissions sometimes take just over 50ms even when nothing is wrong. This would reset the connection, causing the code editor to fail.

We shouldn't raise a timeout error so soon in this case, so extend it to a duration that is more likely to represent a stuck state.
