it's the first time I ask for help on CCM, but this problem is too strange.
I bought an external DVD player for my convertible Acer Aspire Switch 10. When I connect the DVD player to the computer, "UJ-850D" appears between the devices.
Manufacturer - Not available
Model - UJ-850D
Model number - Not available
Categories - Optical unit
Description - Not available
Device status: The device works correctly
MATSHITA UJ-850D USB Device
Driver Provider: Microsoft
Driver date: 06/21/2006
Driver version: 10.0.16299.15
Digital signature: Microsoft Windows"
Only "Driver Details" is clickable, everything else is gray. If I try to update the drivers from other ways, it says that the drivers are updated yet.
So far so normal, the problem is when I insert a cd/dvd.
The DVD player makes a strange noise, as if it started and turned off continuously (which it doesn't do on Mac OS). If I try to open E: from "My pc", there is a very long upload that ends with the disappearance of E:, then a warning appears saying: "The last USB device connected to the computer doesn't work and has not been recognized. Advice: Try to reconnect the device. If it is not recognized yet, it may not work properly".
Then "UJ-850D" disappears from the device list and in its place appears "Unknown USB device (device descriptor request failed)" with the yellow triangle. If I select "problem resolution", it says "impossible to identify the problem".
At this point I don't know what to do.
