USB device malfunctioned

by nizwiz0_0 on Sat Jan 08, 2022 1:59 pm

Hi, I just got a USBTinyISP, and I soldered it up.
When I went to plug it in, there was no green light and my computer said "USB device malfunctioned"

When I put my finger on the Atmel chip, it was extremely hot.

They will probably suggest trimming the leads of the components, checking for shorted connections.
And also ask to see a top view of the board.

Correct and you might reflow some of the solder joints and clean up the spatter with alcohol. a top picture will help and a trimmed and cleaned bottom picture.
