Hi,
I have a Teensy 2.0 board and it stopped working. When I first connected it to the host (Windows XP Pro 32-bit SP2) the LED started blinking and everything seemed to be OK. Then I started the Teensy loader and pressed the reset button. I got the error 'Power surge on USB port' and nothing happend. I tried to use an USB HUB with an independent power supply but the problem persisted.
I solved the power problem by using an USB cable intended for an external USB HD. It has two USB connectors (to the PC) for additional power for large drives. After connecting the board the LED blinked normally. However, when I started the loader and pressed the reset button the LED stopped blinking but the loader did not recognize the device (it kept on telling me to press the reset button). I tried it a few times w/o success. After the last trial something happened to the board. When I connect now (using the same PC and cable) the LED does not blink and nothing happens when I push the reset button.
I have searched this forum and tried Google with different search terms but I was unable to find an answer to my problem. I have tried the only suggestion I could find, i.e. restarted the PC, fired up the loader and connected the board while pressing down the reset button. This did not help either, the loader still said to press reset and the 'Operations->program' menu item was grayed out.
I would appreciate getting some suggestions about how to make my board work again or how to determine if it is bricked.
Thanks!
