From: yandiz on 8 Jul 2010 15:44 Dear All, I made a composite USB with Virtual COM port and HID keyboard. It works fine on W2K/XP/Ubuntu, but it does not work on Windows 7. I've tried everything, but nothing works (This device cannot start. Code 10). To make things worse, Windows 7 is too dumb to recognize the HID keyboard, which does not happen in XP/2K (they recognize the HID keyboard, even without a CDC .inf). Please help. Thanks in advance. --- frmsrcurl: http://msgroups.net/microsoft.public.development.device.drivers/

Are you using your own drivers, or strictly stock drivers? Code 10 means that the driver returned an error code while it was starting up. Windows 7 is much pickier about the USB spec compliance than previous versions. Is it possible your descriptors are not quite correct? What DO you see on Windows 7? -- Tim Roberts, timr(a)probo.com Providenza & Boekelheide, Inc. |
