 Posted: Tue Apr 08, 2003 12:07 pm Post subject: Still have problems with USB Flash disk |
 |
|
I am new in linux while I am proffesional programmer using MS Windows. I decided to go with Gentoo anyway.
I have installed Gentoo easilly without problems. I have now Xfree, KDE and Gnome fully working. I have managed to have Greek keyboard and Greek characters (I am form Greece J). I have also installed my CDRW and DVD as sr0 and sr1 (using scsi-ide). I still have big problem with my 64MB USB-Flash disk (by WMG).
I have all scsi and usb modules compiled.
First, I used gentoo-sources kernel. After booting all scsi modules are already loaded (because of ide-scsi cdroms) except sd_mod. I am loading sd_mod, uhci or usb-uhci (I have VIA motherboard) and finally usb-storage. The green led on Flash-disk turning on showing that disk is iniatilised. Unfortunately after 5-6 seconds the system locks (No keyboard at all) exiting only with hard reset.
I decide to try with vanilla sources. The some thing happens!
Finally with ck-sources seems stable with no locks, but still the Flash disk is not working. Looking the dmesg I see that the system try to assign Flash Disk to scsi1, but fails!
This is my problem. |

Finally I tried vanilla sources patched with 2.4.21_pre7. It seems that this device (WMG 64MB USB Flash Disk) is not supported. 
I haven't locks anymore, but usb-storage gets errors from the device.
For your information, 2.4.21_pre7 working very well for me. |

i had trouble getting my compact flash card to read on my desktop (dual boot, gentoo/xp), but on my server, which i just did over the past week or two, it loads up fine no problem. i haven't booted gentoo on my desktop for a while now though, as i've been using a lot of stuff that's windows only, or a lot easier for me to do in windows at least  . |

Finally after some digging in forums I found it!
The WMG USB flash disk is typical Bulk device, but the manifacturer/product is unknown to usb-storage module.
Adding the following lines in linux/drivers/usb/storage/unusual_devs.h and recompile the kernel everything is OK.
| Code: | UNUSUAL_DEV( 0x0ed1, 0x6660, 0x0100, 0x0300,
"WMG",
"Solid State Disk",
US_SC_SCSI, US_PR_BULK, NULL,
US_FL_FIX_INQUIRY),
|
This may help some of you with problems with Flash disks.
Now I can format my Window$$ partition  |
