Hi,
I'm using modeswitch with two USB MIMO Monzter monitors (v: 0x17e9 p: 0x0288). The usb-modeswitch is able to switch only one device, since the vendor-, product ID and the device class remains the same after switching device. Here is a workaround for usb_modeswitch.c to allow the selection of the device to switch: Code: 87c87 < char NeedResponse=0, NoDriverLoading=0, InquireDevice=1, sysmode=0; --- > char NeedResponse=0, NoDriverLoading=0, InquireDevice=1, sysmode=0, num=0; 253c253 < c = getopt_long (argc, argv, "heWQDndHSOGTRIv:p:V:P:C:m:M:2:3:w:r:c:i:u:a:s:", --- > c = getopt_long (argc, argv, "heWQDndHSOGTRIv:p:V:P:C:m:M:2:3:w:r:c:i:u:a:s:N:", 285a286 > case 'N': num = strtol(optarg, NULL, 10); break; 1275c1276,1278 < right_dev = dev; --- > if((*numFound)==num+1) > right_dev = dev; > 1285a1289 > printf("Device class %02x\n",devClass); 1537a1542 > printf (" -N Number of device to switch\n"); Sample usage: Code: # usb_modeswitch -v 0x17e9 -p 0x0288 -u 1 -N 0
# usb_modeswitch -v 0x17e9 -p 0x0288 -u 1 -N 1 |

Thanks for the quick fix!
I'm planning to incorporate a check for the current configuration which will hopefully work in the same way as the TargetClass check (something like "TargetConfiguration"). This should then work for any number of devices. Can you tell me more about these USB monitors? What is their initial configuration? I see you are setting them to configuration 1 ... |

I have completed a new package which includes the check for the current device config setting.
Can you try the test version? http://www.draisberghof.de/usb_modeswit ... c3.tar.bz2 It will only accept devices for treating that have not set the desired configuration. So it should work for multiple devices. |
