I totally concur on this subject. Poor choice in design to use micro USB for anything but desktop products. Clearly, the engineers coming up with this solution was nowhere near musicians. Tools for musicians should be designed by/or in close collaboration with musicians! In my case, the port in the unit sits tight, but the contact on the cable fits very poorly, only halfway in, and loose and wiggling. Even the slightest movement make it powerless. This is total crap and I am very disappointed with Line6 on this product. It is now being returned to the retailer for a refund.
