This isn’t possible with the imp, there isn’t a USB host interface available.

There may be a hardware solution that works. FTDI has a chip that makes an USB host interface avaiable at an SPI port available. Typical application is to add an USB port to a micro controller. Here is the link: http://www.ftdichip.com/Products/ICs/FT121.html. Digikey has the chip on stock: http://www.digikey.com/product-detail/en/FT121T-R/768-1167-1-ND/3881012 .
Good luck.

Thanks foehrr - thats fascinating. Low cost Usb Host capability opens another whole method of interfacing. There is a simple test board UMFT121DC with some drive software, seems simple enough, though when I’ve looked at past USB Host CDC processing the software got complicated quickly.
