AFAIK it's not possible since the driver keeps checking that it's turned on every second or something like that, and it's impossible to override.

well, would there be a way to connect like 3 or more leds on one single usb port in order to make alerts for different stuff? and how would they be synchronised with LFS ?
like one for blue flag, one for yellow flag, one for shift, etc.

I have just mounted my 35cm wheel with the adapter I recieved from rtsbasic.

Pictures say as much as a thousand words.

i found that the adapter i got with my wheel off RtsBasic was rubbish so i made myself a aluminium one and its so much better it has no flex and is centered

Rubbish? Try making better than that by hand If you have access to equipment to work with alloy, more power to you I guess.

I don't have any flex (with the adapter)

perhaps i will keep Rtsbasic in mind when i eventually get a dfp
