USB and Ethernet not working after high voltage to gpio

[montana_1]

i was experimenting the other day with my pi and now it seams i have broken my USB and Ethernet ports they do not respond in any way to anything. in my experiment's it is possible that i shorted the gpio pins and/or sent over voltage into the pins, up to maybe even 12.

if anyone has any idea's help would be greatly appreciated

Sorry to hear it. It's quite possible that your Pi is now very sad.

If you call one of the Raspberry Pi vendors they will send you a replacement unit ($35 fee applies).

so your saying i need to buy a new pi? i can't even go headless with it not, it can receive no input whatsoever. If i have to buy another one than i will, is there anything i can do with my pi as is? processor, graphics card, and ram seem to be still working fine. It boots but then after i have no way to enter in the password.

There's always serial (/dev/ttyAMA0).

Serial is the one and only way to communicate with the Pi that doesn't involve USB.

I think it would actually be kind of cute to get that working - one way to continue to use the Pi, despite everything else being broken.

can i do this straight from boot and somehow emulate a keyboard?

Yes. Now, getting serial is a bit tricky - but it is fun and a good learning experience.

What I would do (If I was [sic] you), is buy another Pi. They're cheap and it never hurts to have more than one. Also, buy a serial level converter board (you'll have to figure this one out on your own) and get the serial connection working on the new Pi first. Basically, you connect one side of the level converter to 3 of the GPIO pins and the other side of it to your PC (generally via USB).

Once you have all the bugs worked out of the process, you can move it to the old Pi and it should "just work".

Serial is the only way.

Applying high voltage to GPIO sometimes kills the Pi, dunno the chances but maybe it was destiny that gave the Serial Pi
