there are no inexpensive extUSB cables...i don't know where you are but try expansys or amazon in your country...they're all upwards of $20
This http://www.ebay.com/itm/360396058198?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 works well with a dinosaur of an old HTC phone. I was hoping to find ExtUSB with a micro vs mini end but didn't on eBay, hence my question. However this is indeed a generic, inexpensive ExtUSB cable even if the "works with HTC" bit is misleading somewhat. How many years since HTC used mini vs micro connections?
