Hello all,
I'm sorry if the question is allready on the way because they are some allready posted problems for the same USB chipset but i've not found correct solution.
I've an External Hard Disk not working correctly with my Debian 2.6.6 linux box : Shuttle Computer based on Chipset Nvidia NForce2.
The External Disk use the chipset Genesys GL811E :
from the devel mailing list "here are two versions of this chip, GL811 and GL811E. The difference is that the GL811 only runs at up to ATA-4 on the IDE interface (16 MB/s), whereas the GL811E supports up to ATA-6 (66 MB/s, which makes max use of USB-2)."
And for this chip this is an official note from Nvidia:
"Devices that use Genesys GL811 chips may exhibit a failure if a large file is copied. When a file (usually larger than 20 MB) is copied to the USB drive, an error is prompted during the copy transfer. This causes the drive to disappear from the system device manager. Versions 20 and beyond are compatible and will not exhibit this failure."
from http://www.epox.de/_boarddetail/8rda+/nForce2_MCP-T_MCP_USB1.1_AppNote.pdf
and it's the problem I have (excpet under linux I don't have the device manager :-) just time out in log , and no more access to the disk)
So it's mainly a problem in the Genesys device.
A look in the documentation from genesys show me it's possible to use GL811 by giving it at startup a new firware in a live update fashion.
On the same computer I've Windows XP driving this External DISK perfectly. So I can imagine Microsoft driver update the Genesys firware with a good one at each start of the driver.
The Linux USB driver should do that also.
Is this issue allready discuss... ed ? (Sorry my english is bad) is ther are a patch somewhere ?
Thanks you
Stilmant Michael
