Using USB stick in a qemu NetBSD guest on a Linux host

[Carsten Kunze]

Hello,

I am using NetBSD as a qemu guest on a Linux host. I'd like to use a USB stick and tried e.b. "-hdb /dev/sdb" or "-usbdevice disk::/dev/sdb" but nothing works. Has anyone done this successfully?

FYI, remember that disks and partitions within disks are named differently in
NetBSD than in Linux. "/dev/sda" in Linux is like saying "/dev/sd0" in NetBSD.
Maybe that's why you can't see the USB stick inside the NetBSD VM.

I could attach the device with qemu monitor with

usb_add host:<VendorID>:<ProductID>

but then mouse and keyboard does not work anymore.
If I use

-usbdevice host:<VendorID>:<ProductID>

the device is not recognized ...

The USB device is /dev/sde, there is only one primary partition /dev/sde1. I use the option -hdb /dev/sde1. There is nothing in dmesg and usbdevs reports only the mouse. What would be the correct option?

Thank you, it has been a problem with a script I use. It works indeed with "-hdb /dev/sde1".
