Asterisk, GSM modems and VMware ESXi?

Question

Asterisk

Does anyone have experience using chan_dongle in VMware (in my case it's ESXi)?

The problem is this, there are 3 modems.
Of these, one is consistently forwarded in the virtual machine to the USB 2.0 bus, and the rest - to 1.1, but they constantly fall off. The one that works fine on 2.0.
Whether it is possible to win it somehow, to make that all modems were hung up on 2.0?
The controller in the server is, of course, 2.0,

here is the output of lsusb:

At the same time, messages like this are thrown into the console:

option: option_instat_callback: error -71 <br/>
option: option_instat_callback: error -84<br/>

(especially a lot when calling a modem that clung to usb 1.1)
and
option: option_instat_callback: error -108<br/>

Well, the version of the kernel and asterisk, to complete the picture:

Answer 1

You know, I have doubts that the VM is to blame ...
Most likely the voice part is locked in the modem - I had something similar and I cursed for a long time and could not fix it.
It is solved by changing the firmware in the modem.
