I have been following the discussions here quite religiously, and they are very interesting. I recently bought a used C860 on eBay (just sent the payment an hour ago) and am wondering about USB storage.
The reason I am writing this thread is that something in the thread "C860 as usb host by software?" (http://www.oesf.org/forums/index.php?showtopic=4842) caught my attention.
Since then, I have been looking for a cheaper way to attach USB drives to the Cxxx series. I have found a class of products, let's call them external bridges, and I haven't seen much discussion about them here. Here are a few examples:
Could either of these be used so that the regular C860 USB sync cable could be hooked into one end, and the USB drive could be hooked into the other end.
I believe the devices require external power, but are a lot cheaper than going with a USB-CF card. Also, this leaves your CF slot free for additional storage/wireless capabilities.
