Title: Unknown USB (Device Descriptor Request failed) in DS_UMFT260EV1A
Post by: suman.sinha on November 11, 2022, 07:33:49 AM

Hi, I was using the UMFT260EV1A development module for FTDI FT260 to write custom and readback data from the external AT24C02D eeprom connected to the board. I don't know what happened suddenly now when I connect it to the laptop, it gives a malfunction error- Unknown USB device (Device Descriptor Request Failed) as shown in the attachment below. Can anyone please help me?

I tried rebooting the laptop and also uninstalling the driver, but nothing helped.
