Hello @zzxxcv, welcome to the forum.
this could be a Windows Driver system (You didn’t mention which OS and which OS version you are using, I am just guessing).
I’m using Win 10 Home 20H2 with Os build 19042.1052
I have tried all the actions you suggested. I tried to press reset twice when I saw your reply to previous post. When I pressed twice, the unknown USB drive page will disappear. Then when I reconnect USB, it still shows unknown USB.
Windows cannot identify it as a normal USB, just an unknown.
I didn’t experience your problem and I have 6 WisBlock Core RAK4631 here. As you have the problem with 3 different WisBlock Base boards, I don’t think it is a HW problem on the Base boards.
Can you send me an image of the WisBlock Base board like this:
Hello @zzxxcv ,
To check your USB drivers please install zadig: https://zadig.akeo.ie
On zadig menu click on Options-> List All Devices.
This is the correct driver for RAK4630
I am new here, and I am having similar issues. My RAK4630 was working for a little bit, and now the USB connection is not recognized by the PC. It gets detected when i press the reset button twice and it connects as a drive to the PC (FTHR840BOOT). I tested three different cables, and tried on two PCs and one Linux machine. Anyone seen similar issues?
Good. The bootloader was an old one and had a problem with the USB.
When did you buy the board. All RAK4631 should have the new bootloader already since June this year.
