Rigol DP811 USB dead?

(1/1)

terrance:
Insert any UFD, USB2, USB3, SD Card reader... nothing works. Tested the connector, has 5V supply, D+ D- appears ok, with 20k resistance to V-.

Insert UFD when powered up, no D: appears.

Removed LAN cable, still not working.

Am I doing something wrong? Or is there a known working UFD list, or what?

terrance:
My USB2 UFD has an LED, It does not blink at all, so the DP doesn't even try to enumerate it?

_Wim_:
Did you use FAT32 formatting? What memory size where they? I believe (not sure) they should be <8GB.

terrance:
absolutely, usb 2, fat32, 4GB, and my DM3068 can use it....

That does indeed sound like the USB port has issues in that case. Do you see any traffic on D+ and D- when you plug a stick into the port?
