Hi all...I have a very big problem. when I plug my tab into my pc it recognizes it with no problem until I try it in download mode the I get a message saying that my usb port has malfunctioned. Then I switch back to any other mode and its connects again with no problem until. I don't know what to do. I'm 2.2 and rooted but just want to install cwm or twrp recovery, update to 2.3 gingerbread and maybe flash a Rom. I can't connect to odin or the other when in download mode but they recognize it in regular mode with no problem. Please any help will do.
