First of all, I am aware the PL2303 is not officially supported. I am waiting on the delivery of a CP2102 but it could be a while before I will get them (china shipping and stuff

Since I saw a few people saying that they got it working using the PL2303 and I had one laying around I thought I would give it a try.
I first tested the serial adapter by using the method described in the FAQ (arduino IDE) and I receive the messages.
On the Teensy I have loaded the 4.3 EMUPS4 atmega32u4.hex firmware and have connected the TX to D2 and the RX to D3 and GND to GND.
Also connected a PS4 controller via USB to pc and replaced the usb driver with the libusbk using zandig.
However, no mather what I do, I always get the following message when trying to run GIMX:
C:\Program Files\GIMX>gimx -p COM3 -c Dualshock4.xml
option -p with value `COM3'
option -c with value `Dualshock4.xml'
WaitForSingleObject failed: timeout expired.
can't read packet header
No controller detected.
connector_init failed
Since PL2303 isn't supported I would totally understand it if this would get closed, but any help would be much appreciated.
Thanks in advance!
Kind regards,
Christof
