Инструкция для Sony MZ-R55

Fix:  A lot of the large branded computer manufacturers ship their 
systems with a cutdown OEM version of Windows that does not 
always include all the USB audio components. 
Because this is specific to each manufacturer, you will need to 
contact the one who built your system and ask them to send you a 
USB audio upgrade to bring your version of Windows up to the same 
standard as the retail version. The Digital PCLink does not need any 
special device drivers, using only the following generic Windows 
ones that are usually stored in the listed directories for each USB 
component:

C:\win\inf\usb.inf — driver location for USB Composite Device
C:\win\inf\hiddev.inf — driver location for USB Human Interface 
Device
C:\win\inf\wdma_usb.inf — driver location for USB Audio Device

These drivers are all that is needed to operate the Digital PCLink. 

Problem:  Your Digital PCLink went through most of the driver 
install or all of the driver installation fine, but now when you try to 
select it in the Playback section of the Multimedia control panel, 
there does not appear to be any option for USB audio device.

Fix:  The symptom occurs where large branded computer 
manufacturers ship their systems with a cutdown OEM version of 
Windows that does not always include all the USB audio 
components. Because this is specific to each manufacturer, you will 
need to contact the one who built your system and ask them to send 
you a USB audio upgrade to bring your version of Windows up to the 
same standard as the retail version. The Digital PCLink does not need 
any special device drivers, using only the following generic Windows 
ones that are usually stared in the listed directions for each USB 
component:

C:\win\inf\usb.inf — driver location for USB Composite Device
C:\win\inf\hiddev.inf — driver location for USB Human Interface 
Device
