Hello all, I have an odd situation that maybe somebody has seen before, and has a solution.
?
I have a DR5000 connected to a Dell Optiplex 3020 running Windows 10, version 22H2 via USB.? The PC has eight USB ports, two on the front, and six on the rear. ?Two of the rear ports are USB 3 ports.
?
The DR5000 is running firmware version 1.5.5.
?
If the DR5000 is connected to any of the rear USB ports, Windows flags a message telling me that an unknown device has been connected, citing ¡®Device Descriptor Request Failure¡¯ and the DR5000 doesn't work.? If the DR5000 is connected to one of the front ports, one port displays an identical message, but when plugged into the other port, the DR5000 is recognised and can be controlled from the Digikeijs apps, plus iTrain.
?
I have run USBDeview.exe, which is a clever utility to monitor USB port activity, and it shows all USB devices that have been connected to the PC.? I have deleted the failed connection entries, plugged the DR5000 into one of the rear ports again and get the same message.? If I insert a USB flash drive into the same port that fails with the DR5000, the flash drive appears as expected in Windows Explorer, so my assumption is that the port must be working OK.
?
Has anyone had a similar experience as this?? Does anyone know if the YD9401 chip upgrade might fix this issue? (I have one on order from DCCtrainautomation).? I did consider doing a factory reset on the DR5000, but that is an absolute last resort!
?
Thanks in advance for any guidance!
