Mac crashes when guest connected to USB UART

[rbmisc]

I have an FTDI FT232R USB UART cable I have added to the USB Device Filters in VirualBox 5.0.12. I use this with a program I have in Windows XP guest. When I exit Windows XP, my Mac crashes. I don't remember this crash occuring before I installed El Capitan. I have the latest updates to El Capitan. If I don't have this cable in the USB Device Filters, Windows XP exits fine. I also tried this with guest Windows 10 with this cable in USB Devices Filters and exiting causes my Mac to crash. I don't know if this is a VirtualBox or El Capitan issue.
Here is the panic file generated after the crash.

Same problem here! This is a Xilinx board using a Digilent JTAG programming adapter via USB. EL Cap host, Ubuntu guest. Virtualbox 5.0.12 r104815

Entire host machine reboots when I unplug the device, or power off the device, or even just disconnect from the guest it with the Virtualbox menu.

Talk to Apple about that. They rewrote the USB stack for El Capitan and didn't publish the source code, so we aren't exactly in a position to debug it for you.

They rewrote the USB stack for El Capitan and didn't publish the source code

Wait a minute. The USB stack was part of their open-source Darwin (I can't recall the whole thing now) and with ElCapitan they went to a closed-source model?

Wait a minute. The USB stack was part of their open-source Darwin (I can't recall the whole thing now) and with ElCapitan they went to a closed-source model?

They didn't, but it's complicated. Apple does publish a significant chunk of OS X source code. However, some components never get released (say, the Intel E1000 NIC driver or HD Audio driver) and many are published occasionally. Apple did publish the USB stack source code several times, but the last time was for Mountain Lion (10.8.5 or so). I don't think there's been any statement to the effect that the USB code won't be published ever again, but at the moment the El Capitan USB stack source code isn't available.

See http://opensource.apple.com/ for what is or isn't out there.

OK, I see. Sometimes Apple does not so "logical" stuff. Not trying to justify it, it's just that I've seem it once too many.
