cislovani portu - USB-Serial Controller / cuaU? / COM?

[Miroslav Lachman]

Chtel jsem zkusit do VirtualBoxu dostat seriovy port, ktery je tvoreny 
USB prevodnikem.
V systemu uz jsou da onboard seriove porty

# grep uart /var/run/dmesg.boot
uart2: <Intel Lynx Point KT Controller> port 0xf0a0-0xf0a7 mem 
0xf713a000-0xf713afff irq 19 at device 22.3 on pci0
uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0

Kdyz pridam ten USB prevodnik, tak se v logu objevi

V nastavnei VirtualBoxu se ale prirazujou jako COM1 - COM4
