iPod Classic and iHome IP1C

(1/1)

citizenkeith:
Hello,

My 80gb iPod classic is running rockbox installed by emCORE. When I hook it up to the iHome IP1C, it goes into charging mode.

I found this patch, but for some reason I'm unable to download it. Can anybody point me in the right direction? I've been googling this all morning and can't seem to find the answer.

Thanks!

EDIT: I apologize, this may be the wrong forum. Mods please move, if possible.

I downloaded the patch and there is a massive amount of empty whitespace before any text so it appears to be an empty file unless you check the file size.  Here it is with the 651 lines of whitespace removed:

Oh, I wasn't getting a blank page... I was actually getting the patch code with a ton of white space. Now I get it. Thanks for your help!

FYI, I figured out how to deal with my problem without installing a patch. I simply hold down the menu key while inserting it into the iHome dock, and it bypasses the USB charging. Works great, and I'm now happily listening on the iHome IP1C.
