 Posted: Sat Dec 11, 2004 1:45 pm Post subject: usbstick on /dev/ub/b/part1[solved] |
 |
|
Some time ago I lost the access to my usb-sticks (along with some other things) by emerging something wrong. The most I got fixed, but not my usb-stick.
My usb-stick used to be on /dev/sda1 or /dev/sdb1, but that device dissapeared.
Now, after trying to do the howto's for usb-memory-sticks I still couldn't find an /dev/sda or /dev/sdb, but when looking in dmesg I noticed a /dev/ub/b. I mounted it and it seems to be my usb-stick. Any idea's how this comes?
It works, but I couldn't find anything on the forum about it. (Though I'm not shure the searchfunction likes "/"-signs)

| You selected the "Low Performance USB Block driver" in your kernel config. That uses the /dev/ub stuff. That driver does not require scsi. If you don't select the driver, the older scsi emulating usb storage module will take over. |

| Ah, and which one is better? Not the one I use probably, because there would be more info on the forum? |

| I have not figured that out yet. I use both of them and I have not seen a huge amount of difference. The UB driver's main goal is stability. Speed is not even considered in the code (according to the kernel lists). |

ub is really slow and has some fairly fundamental problems in 2.6.9. i'd at least recommend switching back to usb-storage for now.

| I can't find anywhere "Low Performance USB Block driver" in the config. I browsed through the make menuconfig and in the .config-file itself. Where should I look? |

| It's not in the USB section. Look under the block device section. In the .config file it is called CONFIG_BLK_DEV_UB. |

I disabled it, but now I don't have any way to access my usb-stick. (No /dev/sda) What could I have done wrong? I didn't find plain UHCI or OHCI, but UHCI HCD support (the module is called uchi_hcd, ohci_hcd and ehci_hcd.
I also noticed that my dvd-drive doesn't work anymore. (I think it didn't work even before I disabled the low performance drivers, but it worked before I tried to enabled the usb-stick)
Should I post my .config? Or is the slution clear?
Thank you, |

| If you are not using the UB driver, you need to compile scsi disk into the kernel (or as a module) and select the mas storage option under the usb drivers. |

That module was compiled, but not loaded. Now I added it to the modules.autolad, and it gets loaded, but there doesn't show a /dev/sd*. and my dvd-drive still doesn't work.
The usb-drive gets detected though. Dmesg says | Code: | | usb 1-3: new full speed USB device using address 4 |
when inserting the stick. |

| Sounds like you still don't have the scsi disk module loaded (or compiled in). |

This scsi_mod is the scsi module, not? |

| Looks like scsi is there. What does dmesg say when you plug in the stick? |

this (first line = disconnect, second line = connect)
| Code: | usb 1-3: USB disconnect, address 4
usb 1-3: new full speed USB device using address 5 |
The address keeps increasing every time I connect it an other time. |

| Does it keep repeating that (only with the numbers chaning)? If so, do you have ACPI activated? Some kernels/mboards don't do well with USB sticks and ACPI. |

| A dvd should either show up as an ide device or a scsi device depending on if you loaded the ide-cd or ide-scsi module (or compiled one or the other into your kernel). I don't see either in your lsmod output, so check to see how you have your kernel compiled. |

Ok, modprobing ide-scsi brought back my dvd-drive.
Thank you very much |
