Cannot connect USB device (STM32 Virtual COM port) to guest
Posted: 31. Dec 2011, 17:55
Hi,
I use VB 4.1.8 on Snow Leopard 10.6.8 on CoreDuo (32bits) MacBook Pro.
I configured a USB filter to allow to connect my GPS to a windows XP guest.
When I plug in my device, nothing happens on guest side. If I try to connect device manually, I get following error:
If I use kextstat, It seems that AppleUSBCDC catches this device:
So I've tried to remove kernel extensions from /System/Library/Extension/IOUSBFamily.kext/Contents/PlugIns. Extensions are no more loaded but VB is in trouble: USB device title are "unknown" but for STM32. If I try to connect manually, VB tells me that device is busy with a previous request.
I've tried another USB device (serial/USB converter) and I can successfully connect it to my guest.
Do you have any idea on what could solve this issue ?
Thanks in advance for an answer.
Happy new year for everybody.
Marc
