I suggested a "hack" to outline the source (IMHO) here http://www.mail-archive.com/owfs-developers@lists.sourceforge.net/msg08624.html
Its the same problem, though unsure if it applies to very old versions like 2.7: - the DS9490 doesn't get initialized after a reset-error->chip-reset, i.e. runs on with Power-on defaults (regular instead of flexible speed), which is very deadly on long lines - changing the Slewrate-control - though I cannot tell yet which one is more important.. Still testing.. But both together improved realiability here from hours to days! owserver uptime is 6d currently ;) OTOH, with unslug you might also run into a completely separate thing which I get only using openwrt (trunk) here: there *is* another problem, maybe libusb-related, but I haven't been able to trace this down to a reasonable description yet as it's hard to get..(and the two things above also applied here, making any debugging useless so far..) Still hunting.. If you have coding experience: Help wanted, *I guess* it's somewhere around the usb_interrupt_read not working perfectly same on different (embedded) platforms..
