One of my USB thumb drives died: when I insert it into the USB socket in a Debian computer, the drive powers up and then powers down within a second or so. The only diagnostics I was able to get during this second is this:

After the drive gets powered down again, I get no output.
I need to know the capacity of the drive. Based upon external information (purchase history), I logically deduced it must be either 256 GB or 512 GB. Yes, I also g**gled for “090C:2000” (and found someone else reporting 64 GB for vendor 090C and product 2000). The hull is https://m.media-amazon.com/images/I/51qlBitw2FL.AC_SL1001.jpg or https://m.media-amazon.com/images/I/51tXG+oYzuL.AC_SX679.jpg, without extra information. Breaking the hull would void the warranty for defects (not expried yet, provided I know which drive it is). Any idea which capacity the drive has or how to find it out?
udisksctl monitor gives me no capacity either.
