It would be nice if @kotc could test it in his VM.

| libusb_init(&ctx); |

Do we need to check for error code from libusb_init() too? http://libusb.sourceforge.net/api-1.0/group__lib.html#ga9517c37281bba0b51cc62eba728be48b

Tested-By: @kotc tested in virtualbox@win7_64 (debian64 gues), vm was detected and warning printed ok @apritzel: yeah, in cpuinfo: flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx lm constant_tsc rep_good nopl pni ssse3 sse4_1 hypervisor lahf_lm |

Should we merge this as-is or try to implement @apritzel's suggestion? |

Okay, I will push this to the master branch in a few days. |
We try to detect virtual machines by parsing the vendor IDs of all USB devices, and will print a warning message if such an environment is encountered.
