Created attachment 91247 [details] unusual_devs entry The problem and different patches have floated around for some time. I now noticed that a fix for this have appeared in 2.5.68 +UNUSUAL_DEV( 0x0a17, 0x0004, 0x1000, 0x1000, + "ASAHI PENTAX", + "PENTAX OPTIO 430", + US_SC_8070, US_PR_CBI, NULL, + US_FL_FIX_INQUIRY ), http://www.geocrawler.com/mail/msg.php3?msg_id=9914734&list=4563 + US_SC_8070, US_PR_CB, NULL, + US_FL_MODE_XLATE|US_FL_FIX_INQUIRY http://www.mail-archive.com/linux-usb-devel%40lists.sourceforge.net/msg12594.html + US_SC_8070, US_PR_CB, NULL, + US_FL_MODE_XLATE|US_FL_FIX_INQUIRY ), http://www.ussg.iu.edu/hypermail/linux/kernel/0210.1/1838.html + US_SC_8070, US_PR_CBI, NULL, + US_FL_FIX_INQUIRY ), What is the difference between US_PR_CB and US_PR_CBI (seems the pentax cams can work with either). The models that needs this are at least: Optio 330 Optio 430 Optio S Use CB (Control/Bulk). The CBI (Conrol/Bulk/Interrupt) taxes Interrupt endpoints and those may have problems in some HCDs (temporarily - I am discussing it with Greg K-H). In any case most devices like CB more. Hi Pete, I've also talked to Greg about this but he wasn't as specific as you were ;=) > What is the difference between US_PR_CB and US_PR_CBI Quite a bit :) It's the way the device talks to the host. I'm going to send him a patch this week once I get some feedback from some other Pentax camera users. The patch I sent to them had US_PR_CBI. If that works for them would US_PR_CB work too? Per, please poke Matt Dharm or Greg Kroah for a backport. We just issued 2.4.20-18 today, cut from latest, and ... no pentax! Hrm... I really cannot advocate it for you without the equipment. Please let me know of any updates. The patch I made is in the 2.4 and 2.5 tree @ linuxusb.bkbits.net. Greg said he won't push it to Marcel until for 2.4.22. I can send you the Pentax bits from that file if you want right now, or do you want to wait until they goes in .22? Please note that I never got any response from Greg if we should use US_PR_CB or US_PR_CBI (which the trees now have). Anyway, it works great for me! I forgot about the situation with the 2.4.22. Many fixes are held up. The patch only adds two unusal_devs.h entries so it's not that massive ;=) Okay Pete, The patch has been in .22pre now for a while. Perhaps you could take the Pentax unusual_devs.h bits now!?! (There are other entries that I think you should add as well from the .22pre file too) CVS 2.4.20-19+. Per, it's a responsibility of a requestor to re-test and close modified bugs. Closing on faith now. Sorry Pete, I didn't realise I was the one that should close it :=) |
