To get from micro B to mini B, http://www.amazon.com/Motorola-micro.../dp/B000Y032X8
miniB to USB-F is common (and the above cable can be modified to switch into host mode for USB keys - a switch between the brown and black wires inside makes it an instant A/host adapter) The mini-B to USB-A-Female adapters are also common.

I found a retractable usb to nokia charger cable at a truck stop / travel center (Pilot, I think), but the ccm accessories (via Amazon, save a bit on shipping) also has a normal to tiny charger adapter: http://www.amazon.com/CA-44-Nokia-Ch.../dp/B0009RFX24

I have some other accessories that use the larger charger, so this allows me to charge the tablet too.
