I must be cursed.
So I go to Jurong Point to buy my USB hub. With the help of Ban Xiong, who is going to meet an unspecified friend for dinner, I pick out a small USB hub which needs no external adapter. I go home, boot, and plug in my hub. Everything freezes. Then when I reboot, my monitor refuses to get the signal from my CPU, and it sounds as if it isn't booting properly.
*buries head in hands* The feng shui in my computer room must be very bad.
