Hi, I even get the following with cat /proc/partitions command major minor #blocks name
8 0 126976 sda 8 1 126960 sda1 I am unable to mount the device. Hence I cannot use it. I have vfat driver loaded in the kernel. Moreover we are using customized kernel and so we do not have udev or MAKEDEV. Let me know if I am wrong in interpretation. Also can you please highlight the exact steps to mount the usb device? It would be really helpful. We used the major and minor numbers obtained from /proc/partitions and tried to make device nodes using mknod /dev/sda b 8 0 and mknod /dev/sda1 b 8 1. This creates the nodes but we are not able to mount using these entries in /dev. Please help.

They show up because a real SCSI bus can support up to 8 or 16 targets, but the USB mass storage protocol allows for only a single target. So when the SCSI core tries to probe for additional targets, those debugging messages get printed. > I also get "Attached scsi removable disk sda at scsi0, channel 0, id 0, lun > 0" in these logs. Still no entry is made in /dev regarding sda. That's because the kernel isn't responsible for creating /dev/sda. You are. Or if you use udev, then udev is. > I need to mount the drive and without this entry in /dev I cannot do so. > > Please let me know how shall I procede. If you're not using udev then you may need to run the MAKEDEV script or something equivalent. Tell it to create the sd[a-z]... device entries.
