Timeout Problem with Raspberry Pi 5 USB Port Output

[Mickey70]

Everything looks correct for USB port configuration, but when I try to write any amount of data out of the RP5's USB port, I always get a time-out error. Any thoughts most welcome!

More background. I wrote a simple Arduino script to have the Mega2560 echo whatever ASCII I sent to it via a USB connection between my PC and the Arduino. On the PC, I used Putty over a serial connection to type in the characters I wanted to send. The echo worked fine. I next took the same Mega2560 and connected it to my RP5 using the same USB cable. As stated in the first line above, writing out on the RP5's USB port ALWAYS times out.

This seems to have nothing to do with pyusb.

You should use serial connection and pyserial is a good one to use if you prefer to use Python.
