1Some things that need to be done: 2--------------------------------- 3 4High priority: 5-------------- 6 7On a short control transfer the status phase needs to be executed anyway. 8 9Fix flow control in ucom (copy from com driver). 10 11Use some encapsulation in the upl driver to allow multiple protocols. 12 13Get the uezcom driver (with Doug Ambrisko's firmware) running. 14 15 16Bug reports: 17------------ 18 19Bernd Ernesti's problem: host controller halted with umodem 20 21umass problem with Ricoh flash reader 22 23wskbd for X 24 25mel kravitz's problem, lockups with disk and printer 26 27Aaron's problem: Test aue with ohci. 28 29 30General: 31-------- 32 33Figure out why uvisor is so slow. 34Try to get specs, and check if Linux driver is really right. 35 36Do bandwidth accounting. 37 38Throw out more USBDI gunk. 39 40Make hub driver notice transition between self and bus powered state. 41Some hubs change the number of available ports on this transition. :( 42Handle overcurrent conditions. 43 44Make it possible to open any device in a "generic" way, i.e., like ugen. 45Perhaps usbdevfs? 46 47Rotate the QHs for bulk transport to get fairer scheduling. 48 49Change HC drivers to queue multiple request for an endpoint 50to get better performance. 51 52Do memory deallocation when HC driver is detached. 53 54uaudio problems: 55 mixer names are awful, use some heuristics. 56 implement selector units 57 debug input 58 test with more devices 59 60Stylistic changes: 61 use usb_ and usbd_ consistently 62 rearrange the contents and names of some files (Nick) 63 64Use splsoftusb() or a thread to deliver callbacks. 65 66Add threads to the Ethernet drivers. 67 68Change what's done at watchdog timeout inb if_{a,c,k}ue.c; what we have 69now doesn't work because it's done in an interrupt context. 70 71Factor out the common code from the Ethernet drivers and reuse that. 72 73Get rid of hcpriv. 74 75Keyspan serial driver 76 77Clean up umass driver 78 79 80Documentation: 81-------------- 82 83Document device driver API. 84 85Document HC driver API. 86 87Update ugen(4) 88
