Well, Device manager is a separate thing. I forget where the drive letter assignments (or removing one) are in Windows 7/10/11.
However, it looks like either Windows has a problem or the Kindle has.
VID_1A40&PID_0101\6&1eb6a6e8&0&2 etc is info unique to maker and model of device.
Except that VID and PID is the ID of a USB hub, not a Kindle. See:

From MS site

Single-Interface USB Devices
When a new USB device is plugged in, the system-supplied USB hub driver composes the following device ID by using information extracted from the device's device descriptor:
USB\VID_v(4)&PID_d(4)&REV_r(4)
Where:
v(4) is the 4-digit vendor code that the USB committee assigns to the vendor.
d(4) is the 4-digit product code that the vendor assigns to the device.
r(4) is the revision code.

So you DO have communication on USB.
According to MS, this CAN be caused by improper eject, ancient BIOS, bad device driver etc (One dodgy suggestion is to try Windows Repair) or an incompatible device. The Kindle doesn't need any special device drivers.
If a USB memory stick works AND the Kindle won't work in another PC OR "removing" the USB port in Windows Device Manager doesn't work (Reboot and it will automatically be added again), it's likely a faulty Kindle.
Do try a USB hub in-between in-case all the PCs have very fancy USB3.0 ports or something. Sometimes that works.

11. Replace the hardware. A problem with the device itself might be causing the Code 43 error, in which case replacing the hardware is your next logical step. In most cases, this is the solution to a Code 43 error
