Hello, we have some trouble with reading files from a CD. The same physical media works fine with 2.6.0-test7 (no IO errors). But it fails with all 2.4 kernels. I added some debug and things start to fail in usb_stor_transfer_partial() due to result == -ECONNRESET.
The used CD-Rom drive is: T: Bus=01 Lev=02 Prnt=02 Port=02 Cnt=02 Dev#= 7 Spd=12 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=05ab ProdID=0030 Rev= 1.00 S: Manufacturer=In-System Design S: Product=USB Storage Adapter S: SerialNumber=XXXXXXXXXXXXXXXX C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr= 98mA I: If#= 0 Alt= 0 #EPs= 3 Cls=08(stor.) Sub=02 Prot=50 Driver=usb-storage E: Ad=01(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms E: Ad=83(I) Atr=03(Int.) MxPS= 2 Ivl=2ms System is a dual xeon 2.4Ghz, 512mb. If I understand the code correctly, this -ECONNRESET is caused by the USB layer, not usb-storage. The code to modify ->status in usb_stor_bulk_msg(), us->current_urb->status == -ENOENT does not trigger, the result from usb_submit_urb() is also ok. How can I debug this further? Is an interrupt handling (acpi?) or similar problem? -- USB is for mice, FireWire is for men! sUse lINUX ag, nÜRNBERG ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
