I've done some tests:
- it doesn't matter which port I plug in the mobile wifi - suspend will fail
- if the mobile wifi is turned off, suspend works fine (no suprise here)
- plugging in my usb stick, doesn't have a negative effect
- plugging in my external hard drive, doesn't have a negative effect on suspend
Some information about the mobile wifi:

sven@svenBlack:~$ lsusb -vs 001:007
