<USB/IP> [Report] cannot cancel isochronous transfer normally

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi!
 
I check the movement of the Web camera using USB/IP.
The inspection environment is as follows.
 
 
[Client]
         OS: openSUSE 12.2 (Based on Linux kernel ver.3.4)
     USB/IP: Upgrade to based on Linux Kernel ver3.6  @@latest@@
             http://lxr.free-electrons.com/source/drivers/staging/usbip/
 
     Device: Web Camera (UCAM-DLS30HSV)
Application: guvcview (ver.1.6.1-2.9)                 @@latest@@
 
             
[Server]
         OS: openSUSE 12.1 (Based on Linux kernel ver.3.1)
     USB/IP: Default
             http://lxr.free-electrons.com/source/drivers/staging/usbip/?v=3.1
 
 
##########                     ##########
# Client #--------[HUB]--------# Server #
##########                     ##########~~~(Web Camera)
          <Link Speed :100Mbps>
 
 
<<Reproduction procedure>>
 
##Client side##
 Step1 :Import Device(Attachment)
 > usbip attach -h xxx.xxx.xxx.xxx -b y-y
 
 Step2 :Application start
 > guvcview
   --> [GUVCViewer Control]Window and [GUVCVideo]Window open.
 
 Step3 :Repeat a resolution change and a frame rate change.
 [GUVCViewer Control]Window
    -->[Video & Files]Tab
       -->"Frame Rate:" and "Resolution:"
 
 
<<Phenomenon>>
 
 Application(guvcview) is hung up.
 However, the data transmission(isochronous transfer) of a client and the server continues.
 
 
<<Cause>>
 
 Isochronous transfer is not canceled normally.
 
 
-------
 
Is this a bug of USB/IP?
Or is it a bug of guvcview?
 
Please confirm it and please give an advice!!
 
Thanks.
