Hi, Some doubts about the probe handler . When is the probe handler of the usb device actually called. Suppose that before my usb driver is loaded in memory, the usb device is already attached. Will the probe function be called after i register my device using usb_register in my usb driver. Or is it that the probe function is only called when a new device is attached after i load my driver.?
Secondly for sending a URB the usb_submit_urb function is used with the data, to be sent with request, as a pointer in transfer_buffer. When should memory be allocated and freed for this transfer_buffer. Can it be freed just after usb_submit_urb returns??Or do we have to wait till the completion handler is called?? If anyone knows about this do reply. Thanks in advance and regards, Dattaram. -- Get your free email from www.linuxmail.org Powered by Outblaze _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
