@all
For all having a USB gadget based on a PL2303 chip
here a beta driver for these devices.
The driver is far from finished! So your mileage vary and be prepared that it crashes.
The driver writes a lot of debug message to via the Exec DebugPrintF (normally written
to the serial port), so if it crashes or don't behave as expected, include the debug
output with the description what failed.
If you have a variant of PL2303 you can / must adopt the pl2303.fdclass file (is a text file)
and adjust the vendor/product id.
To see a list of theoretically
supported variants take a look at the linux sources.
Have fun and I hop get a feedback to improve the driver.
