I turned it on with NO USB and held select - B: FF
Then I plugged in the USB and have the same - B: FF
On my e200v1, with no cable connected, I get B: EF
And when I connect the cable, I get B: FF
This confirms that you have a stuck bit that Rockbox uses to detect USB mode. This is a hardware issue.
With some modifications to Rockbox, you may be able to get it to boot to the main menu with no keypress, go to charge mode with the select (like current operation), and enter USB mode with another (maybe REC).
Thanks. It still auto selects V2 even after installing Rockbox software for V1.
In Rockbox Utility, on the main screen, click the change button. On the Configuration screen, press the Autodetect button on the bottom. With my e200v1, it autodetects correctly. Click OK to save the selected device. After you exit the program, it will retain your selected device.
