Re: [Bulk] Re: FS#41424 - Virtualbox 4.3.14, USB doesn't work flawlessly

Hi,

I have also issues with USB devices on Windows 7 32Bit guest. The
devices I use are mainly USB Serial COM ports. On top of that a
proprietary binary protocol is used.

The applications that communicate with the USB Serial COM ports are
constantly having problems reading and writing data.

Installed:
virtualbox 4.3.14-3
virtualbox-guest-iso 4.3.14-1
virtualbox-guest-modules 4.3.14-5
virtualbox-host-modules 4.3.14-5
Linux localhost 3.16.1-1-ARCH #1 SMP PREEMPT Thu Aug 14 07:40:19 CEST
2014 x86_64 GNU/Linux

Extension Pack 4.3.14r95030

With usbmon and wireshark I could see a lot of malformed USB packets.
I'm afraid I don't know enough to make an exact conclusion whats wrong
in detail.

I will try a downgrad from 4.3.14-3 to 4.3.12 and report again.
