I am using Virtualbox 2.2 in Kubuntu 9.04 host. USB hard disks are working at guests (connect, disconnect etc), but speed is about 2MB/sec, so say USB 1
Is there any workaround? Thanks
USB is working but no USB 2

Re: USB is working but no USB 2
How do you enable usb support in VirtualBox, there are two ways today, either you mount usbfs under /proc/bus/usb or you don't. If VirtualBox finds usbfs mounted under /proc/bus/usb it will use old deprecated code, if not it will use newer code.
This might impact speed, so go have a look, do you have an usbfs entry in fstab and do you have a mount -a or mount -usbfs command in /etc/init.d/boot.local, if so comment out those lines reboot and see if there's any gain in speed. The newer code should work under Ubuntu 9.04!
