I'm finding it extremely difficult to remove a USB device from my MBA USB port. At times I can't get a firm grip on the plug itself and I end up pulling on the cable b/c there's not enough room on the plug itself to remove it easily...
Nope, no problems here. Sometimes I can't plug a usb device in because it doesn't clear the bottom of the MBA case, but anything I can plug in is easily removed.
Is it possible that your device is actually pinching up against the case itself, and that's what causes the difficulty?
No, not pinching, since I don't want to scratch my MBA or the USB device. When I'm syncing my iPhone, connecting the SuperDrive or using my magicjack phone, I find that the USB connection is very tight and I have to use a firm grip and wiggle it off, rather than just pulling it off, and sometimes it slips out of my grip...
