USB/EHCI transfers sometimes time out

[axeld]

After Luzern, I updated my USB installation again, and since then I have serious problems with accessing USB mass storage devices. Some blocks/files whatever are listed in Tracker, but cannot be accessed, reading their data fails. It's even 100% reproducible with the same files. I have these problems with HDs as well as flash memory cards. Log file from a failed transfer is attached; the problem occurs at the end of the log.

Just tried with r21904, but the problem persists. It might happen only on certain disks (I didn't have that flash disk before, and only rarely used that HD).

Which version of usb_scsi do you use? The one from bebits has some problem during converting READ_6/WRITE_6 to READ_10/WRITE_10. Patched version is here: http://zharik.host.sk/prahramy/usb_scsi-0.1.0-dev-9994.zip. Can you try it on your system?

I thought I would be using the latest version from Haiku's repository that allowed to be used with BeOS. Anyway, with that new version, the problems are gone, thanks!

Does the version in the repository still suffer from this problem? If not, I would just close this bug.

Hm... it looks a bit suspect. Actual repository code already have this fix for 6-->10 conversion. Please left this bug opened until I check my working copy, that is targeted to cvs at sourceforge. It is possible that it still have some changes, that are not commited. The version, we have now in Haiku repository was transferred directly from my CVS at sis4be.sf.net.

It (or something very similar) just happened again, attached another log. It just doesn't seem to happen very often anymore, now.
