Hi , I m currently working on a USB device driver in Linux (redhat kernel 7.1, 2.4.2-2).The USB driver is carrying on the data transfer (ftp sessions)and i plug out the USB device.my machine just freezes . I cant use mouse or keyboard . I have to reset my PC . However I am not able to produce this problem when i m carrying on the ftp sessions in the non-desktop terminals . The problem happens inconsistently in the Gnome desktop environment.I say inconsistenly because sometimes even if i Plug out and Plug in the usb device several times during ftp sessions the PC doesnt hang.The problem doesnt occur always. Also I m unable to find whether there is some problem with the driver, the Gnome environment or the host controller. I m using the uhci controller. Kindly let me know if anyone has some solution or a method where i can find where the problem lies.
Also i have debugged my driver. In the hang scenario the logs obtained show that the usb-drivers "disconnect handler" is completely executed . Hence the control is outside the driver.
