proxmox 5.4
AMD Athlon(tm) 64 X2 Dual Core Processor 5200
IOMMU is included
virtual machine Ubuntu 16.04.
The scanner of Mustek Scanexpress 1200UB Plus is connected
Pass USB Vendor\Device ID .
05d8:4002
For scanning I use the scanimage utility.
The scanner is connected through USB interface 1.1
Without virtualization it works at the same hardware quickly.
After transfer on proxmox the server began to scan by 10 times more slowly.
Load of the processor about 10 percent.
Something strongly slows down work on USB. In comparison with normal hardware.
In what can the problem be? Any ideas.
