My system information shows the USB: MiniPro TL-866 Programmer : Product ID: 0xe11c Vendor ID: 0x04d8 (Microchip Technology Inc.) Version: 0.00 Speed: Up to 12 Mb/sec Manufacturer: Location ID: 0x14400000 / 1 Current Available (mA): 500 Current Required (mA): 100 The only other thing that I can think of is OSX Maverick compatibility or security feature. I also tried the above attempts with 'Enable USB 2 (EHCI) controller' ON/OFF with both VB revisions.

Sometimes publishers take a little while to make this information available, so please check back in a few days to see if it has been updated. Also, if you want to be able to view USB devices from your OS X Mountain Lion virtual machine, download the Virtualbox Extension Pack and run it before. Com este pacote, pode emular sistemas operativos como o Mac ou Linux e utilizar todas as. O processo de instalação é muito simples e é realizado diretamente a partir de Ficheiro>Preferências>Extensões. If I replug in the usb I can repeat the process with the same results. We dont have any change log information yet for version 6.1.34 of VirtualBox Extension Pack. O VirtualBox Extension Pack é o pacote que o VirtualBox necessita para suportar USB 2.0, o VirtualBox RDP e PXE boot para placas Intel. If I return to the drop down menu and try enable it again I get an error message stating that the device is servicing another request - I assume it's referring to the initial request. I can see the MiniPro as a choice in the device drop down menu, but when selected it will not put a check mark next to the device. I tried using 2 older Virtual box revisions (4.2.22 and 4.2.20 ) along with their respective extension pack but I still could not get it to 'usb pass through'.

Virtualbox extension pack 4.3.6
