thanks its probably a dud miner. Zadig doesnt detect it to update driver. have checked everything except a different usb cable.
the troubleshooting steps that guide offers for the R909 is if it doesnt work restart it XD.
the software i was refering to was zadig as well as other usb software ive used to try to detect the device.
Is there any sign that the unit has power(LED lights and a fan spinning)?
If it's running then maybe the USB cable is defective you need to replace it since that's the only one that you haven't tested yet or it could be the USB port is broken try to clean it with isopropyl alcohol and brush or replace the USB port.
yes it boots up, fan, leds. and motherboard leds. i tried to connect it to me server running truenas. it freezes the server XD, it wont even boot if plugged in. so not sure if thats good or bad. but it tries to do something. ive got a new cable ordered and will see if that does anything.
