I'd like to buy an adb to usb adapter if you have one email me at
ADB to USB? They don't exist and can never exist for a number of reasons, mainly being that the pins don't equate any way you put it and ADB ports are 9.6k/s max (I think).
Just to clarify the issue: There are devices that let you plug an ADB device (keyboard, mouse, etc.) into a computer's USB port. As moosemanmoo says, there are no devices that let you use a USB device on the ADB ports of an computer.
