Hi Nils et al,
So where do I find those tools you mention? I see you added some links in a second mail, but with which one should I start? ;-) > http://www.flashdrive-repair.com/2017/10/chipgenius-v417-software-2017.html > http://www.flashdrive-repair.com/2017/10/lacie-usb-disk-storage-format-tool-v5.3.html > http://www.flashdrive-repair.com/2017/10/flash-drive-information-extractor-v85.html > http://www.flashdrive-repair.com/2018/09/45-way-to-repair-corrupted-usb-flash.html > One of those tools I've seen in those stick-tests was able to write > configuration data on the stick's controller.

I had opened the stick to check the wiring, but the loose contact was only in that Windows 10 PC, neither in the stick nor in my own PC. I do not think the other personality of the stick is USB gadget, as it is rather old, as Jim has already guessed. Still it did somehow get puzzled and changed something... Maybe it entered some sort of security or update mode? The controller is USBest UT161-T6G PCA041 0613BA. There are also 6 resistors, 6 capacitors, 1 LED, 1 crystal (12 MHz) and two memory chips "Japan C66411 R1FV04G13RSA" which differ in their other markings: One says 05 53 M82690, the other 06 04 A81842 with a "ROM USE ONLY" stamp on it which might mean a reduced reliability for writes... Of course it would be possible to buy another stick, but the technical details of WHY it can still show up as USB device, but no longer opens as storage, are intriguing enough to ask.
