Can I repair a physically broken USB drive?

My friend just wrote to me, all in panic, that he had broken his USB with his math homework for tomorrow. (Yes, no other backups, just that.) It looks like this now:

Is there any way that I could fix this? My thinking is soldering it together but I want to hear if anybody has experience with this or any tips?

Another option would be to see if Word…

How to see if USB stick has MBR?

I have a USB stick supposed to be bootable, but the computer does not boot it. I suspect that there is no MBR (Master Boot Record).

Is there a way that I can power off a (specific) USB device completely using software from a Linux machine?

I want to use this to power off (so that the LED is off) a (single) USB stick.

Do you know any method to achieve this? E.g. using /sys/bus/usb or the like?

Here is a summary of my findings so far:

Some keys have a switch which makes them read-only. Unfortunately this is not…

Why Do Some USB Cables Have Two USB Connectors at the End?

I’ve recently bought an external hard drive enclosure and it had arrived with an USB cable, with one USB connector on one side and two on the other. Why do some USB cables have two connectors while others do not?

Verifying USB connection speed (USB 3 or USB 2?)

I’ve purchased several new USB 3 capable drives to use with my new (USB 3 capable) laptop. They connect ok but I suspect they’re silently falling back to USB 2. The sustained transfer rates I’m seeing are around 30 Mb/s for both reads and writes, well within the practical limits of USB 2. One of the drives in particular is rated for transfers well…
