[Q] GT-S5360 Android 4-4-4 KitKat Tutorial: Drivers and Help Needed topic

I've successfully installed the LiquidSmooth ROM on my Kindle Fire HD, so now I'm keen to update my Samsung Galaxy Y GT-S5360.

I've read this tutorial, which seems to be written for my level (newbie). However, when I switch my S5360 into USB Debugging Mode, Windows 7 64-bit can't find the drivers; Device Manager shows this:


It needs drivers for BCM21553-Thunderbird, CDC Abstract Control Model (ACM), and CDC ACM Data

Any suggestions?

Also, any comments on the above tutorial?

I'm doing it on a spare phone first, but I will need to backup my real one.
