Unfortunately, the drive could not be installed. Even extensive efforts were unfortunately unsuccessful. On a Windows 7 machine it worked perfectly, but I did not buy the stick. I suspect there is a problem with the driver, who could not be installed clean also. The stars are there for the great support and service of the company AVM, because there is absolutely nothing to criticize and this is rare and worth despite the faulty driver a praise in this day and age. Reimbursement was also easily and quickly possible.
