根据 lsusb 的输出确定坏掉的 USB 拇指驱动器的容量

我的一个 USB 拇指驱动器坏了：当我将它插入 Debian 计算机的 USB 插槽时，驱动器会通电，然后在一秒钟左右内断电。在这秒钟内我能够得到的唯一诊断信息是：

# lsusb -vvvvvvvvv -d 090c:2000

驱动器再次断电后，没有输出。

我需要知道硬盘的容量。根据外部信息（购买历史），我逻辑上推断它必须是 256 GB 或 512 GB。是的，我也搜索了“090C:2000”（发现有人报告供应商 090C 和产品 2000 的容量为 64 GB）。船体是https://m.media-amazon.com/images/I/51qlBitw2FL。AC_SL1001.jpg或者https://m.media-amazon.com/images/I/51tXG+oYzuL。AC_SX679.jpg，无需额外信息。破坏外壳将使缺陷保修失效（尚未过期，前提是我知道它是哪个驱动器）。知道驱动器的容量是多少或如何找出它吗？

udisksctl monitor也没有给我任何能力。

和以下故事相同https://unix.stackexchange.com/questions/644696/usb-memory-stick-unmounts-and-vanishes谁报告说是256GB

此人有一个类似的 USB 记忆棒，并报告说问题可以解决https://www.linuxquestions.org/questions/debian-26/can-not-mount-drive-4175432442/page2.html
