Hi, Not sure if this is the ideal place to post but... I have a Analog Discovery 1 that is no longer detected by my PC (Windows 7 laptop). Nothing shows up in the Device Manager list when I connect it via USB, either directly to laptop or via externally powered USB hub. I noticed there was a bit of give on the USB connector so I opened it up and found some of the USB mini connectors pins had lifted slightly off the PCB. I re-soldered all pins and to the best of my efforts there doesn't appear to be any solder bridging and the connection looks ok. My validation for this was a continuity test to check that the pins on the free end of a connected cable beep on the relevant solder pads of the USB mini connector and some adjacent components that l assumed might be connected to either USB 5V or GND. With the USB mini connector pins fixed I retried but still cannot get the PC to detect it when connected. I wasn't sure if Attila's comment about ferrite beads was also relevant to the Analog Discovery 1. I did notice that beneath the USB mini connector on the other side of the board there are 2 ferrite bead looking components. A continuity test between one leg of the bead to the other beeps (for both of them), so I assume that means they're ok but I'm not sure. Just want to know if anyone can suggest other things to probe that might revive this box? Thanks in advance!
