| 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? |

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.... |
