Question about XQD-USB-Adapter - 154615

The QDA-SB1 XQD comes with a short USB extension cable. The reader itself seems to be the same. This allows somewhat hidden USB ports to be used. Above all, however, the reader without the cable protrudes approx. 6 cm from the notebook/PC. If accidentally bumped, the USB port in the notebook/PC or the mainboard can easily be damaged.

I don't know what the difference is. But with this one, the import keeps interrupting. Very annoying. It's like that for me and also for a colleague.
The reader also gives the impression of cheapest Chinese production.
