Hi, I am writting USB driver in slackware 10.2, i.e. 2.4.31 kernel. My USB device has 3 bulk endpoints. One bulk-out and 2 bulk-in. i am using devfs file system to craete device node for this device. When i initially connect the device, everyhing works properly. But when i disconnect the device( when an application on this device node is open, it is excepting some input from user to send it to driver)suddenly and connect it again disconnect()function is called but probe() function is not called. I varified the code of releasing the resources in disconnect and close. i felt its proper. Can somrbody please tell me whats wrong i am doing. One observation - If i dont fill and submit one particular URB ( for one particular endpoint.no 6) probe is called many times as u disconnect and connect. Bit if i submit this urb, probe is not called second time. There are lots of memory allocation done in the callback function of this endpoint.no.6. I checked whether they are being freed properly or not. Whats wrong i am doing, please suggest me. Thanks alot in advance Savita
