Yes it was odd as I tried three different cables but all of them would not fit fully into the slot. The plastic surrounds on each of them were catching the edge of the cybook. The only cable that fit fully was the one that was pared down. I couldn't get any of the rest to slide fully into the usb slot on the device. I haven't gotten a new mini-usb cable in about 3 years though so perhaps they just made them with wider surrounds. At least it works though
