After apply GPO with Removable Storage restriction policy, USB devices rapidly disconnect and reconnect

Greetings.

I have a GPO's to control Users access to removable devices.

DC: Windows Server 2008R2.

PC: Windows 8 Professional.

So, OU "USB TEST" consist of my test user account.

I have 3 GPO, linked to this OU:

USB Deny:
User Configuration (Enabled)
Policies
Administrative Templates
System/Removable Storage Access
Policy     Setting     Comment
CD and DVD: Deny read access     Enabled     
CD and DVD: Deny write access     Enabled     
Floppy Drives: Deny read access     Enabled     
Floppy Drives: Deny write access     Enabled     
Removable Disks: Deny read access     Enabled     
Removable Disks: Deny write access     Enabled     
WPD Devices: Deny read access     Enabled     
WPD Devices: Deny write access     Enabled

Apply for all Authenticated Users


USB Read
CD and DVD: Deny read access     Disabled     
CD and DVD: Deny write access     Enabled     
Floppy Drives: Deny read access     Disabled     
Floppy Drives: Deny write access     Enabled     
Removable Disks: Deny read access     Disabled     
Removable Disks: Deny write access     Enabled     
WPD Devices: Deny read access     Disabled     
WPD Devices: Deny write access     Enabled

Apply for Global Security group "Domain\USB_Read" by Security Filtering


USB Write
CD and DVD: Deny read access     Disabled     
CD and DVD: Deny write access     Disabled     
Floppy Drives: Deny read access     Disabled     
Floppy Drives: Deny write access     Disabled     
Removable Disks: Deny read access     Disabled     
Removable Disks: Deny write access     Disabled     
WPD Devices: Deny read access     Disabled     
WPD Devices: Deny write access     Disabled

Apply for Global Security group "Domain\USB_Write" by Security Filtering


So, I think that any users, who not in USB_Read or USB_Write groups, will not have any access to USB and other removable devices.

If User was joined to USB_Read or USB_Write group, he will have read or write access to any removable device.

And it correctly works, but with one BUG: When I plug some devices like Cellular with inside SD card, it connect and instantly disconnect. And it continues without stopping. I don't know why. If I disable policy it works correctly and connecting normal.

Maybe anybody know what is going on?
