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