So I am transforming my Nook color into a point of sale system and need USB Host support for serial access (for various peripherals) as well as USB HID access. I managed to get USB host to work on CM 7 ... Keyboard, mouse and my HID credit card reader work but it seems like I can't charge the nook at the same time. Eg draining power while being USB host work great... . I tried creating a Micro to Mini USB adapter that connects the nookcolor to a powered 5v 2A USB hub with attached Point of Sale devices ( card reader, wieless modules, microcontollers/arduino etc... but for whatever reason even with a powered hub I am unable to maintain the nook's charge while the Nook color is in USB Host / External VBus mode... Any suggestions? Does CM9 with Android ICS solve this issue?
Tonight I tried to send 5v directly to the board to see if I can power/charge the nook with no battery and to charge the Nook via a +5VDC so I can free up USB host mode to be able to access any device/peripheral on the powered USB Hub... This should work but I am a bit worried about how reliable USB host support is for Nookcolor
