Hallo
i had installed into my new computer with Motherboard Asus Z170 a PCI card with 4 serial port... SERIAL, not USB....
i have to say first there is 1 serial port on motherboard BUT i need about 4-5 serial port to drive my cutting key machines
if i digit "setserial -g /dev/ttyS*" it display correct info like:

/dev/ttyS0, UART 16550A, PORT 0x03f8, IRQ: 4
/dev/ttyS4, UART undefined, PORT 0xd070, IRQ19
/dev/ttyS5, UART undefined, PORT 0xd060, IRQ19
/dev/ttyS6, UART undefined, PORT 0xd050, IRQ19
/dev/ttyS7, UART undefined, PORT 0xd040, IRQ19

the first is the one on MB, the otres in card, of course it display to me other ttyS but "unknown...
NOW... i had installed inside virtualbox a win10 pro. it work well with usb video, mouse bla bla all...
i had enabled all 4 sderial port with HOST type and i did this
COM1 -> /dev/ttyS0
COM2-> /dev/ttyS1
etc...
when i didn't install the card win10 see find regulary the COM1
BUT
if i install the cart, windows show me yelllow warning on any COM with the error 12
conflict in resources...

i have another serial card but only with 2 ports (i need at least 4)
and when i install it windows say:
COM1 and COM3 conflict, COM2 OK
i'm near become crazy....
plesase help me!!!!

...i hsd try DEFINE uart as in ttyS0 16550A, i had try different irq for any port,
i had try change port address and insert the standard port value for seriual and it say "source busy"
i'm doing all with second account on computer but when i try modify i use sudo before so i assume i'm root when i try modify
i had try open virtualbox as root...
nothing changed

For me it looks like you need first to make sure that the ports work correcly in the host Linux.
"UART undefined" doesn't look like a correct working driver.
When the ports are working and can be used from Linux then you can start trying to pass them to a Virtualbox guest.

Could be card is broken? Or dont work properly? I will search some test... I dont know now how test them...

here what i read trought some commands:

what can i do to try if ttyS* are properly working?

i have some adapters... usb to serial...
i have 6 usb (4x2.0 and 2x3.0) but when i plug them 1 is ok, 2 is ok, but when i plug others i recive a yellow waring on the peripher
about insufficient resources or not existant hardware????????!?!?!?!?!?!?!?
i become crazy...

last update:
i have 3 cards... 1 with 2 ports, and 2 cards with 2 porte each
and i had try installing 1 com with 4 ports or 2 carrds with 2 ports each
same results
(i had disable the com avaible onboard)
into a win10 guest coms work properly just if i enable only 2 and only if i enable COM1-COM2 or COM1-COM2 or COM3-COM4 or COM1-COM4 or COM2-COM3

i had installed WINXP and magically all 4 COM work properly
so i think is a driver problem, seem win10 under virtualbox accept only 2 COM evenif i try enable all 4
someone have a sugestion for me?

thank you
