      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 Add lots of bus_dmamap_sync().
     37 
     38 Do bandwidth accounting.
     39 
     40 Use the pool allocator for TDs et al.
     41 
     42 Throw out more USBDI gunk.
     43 
     44 Make hub driver notice transition between self and bus powered state.
     45 Some hubs change the number of available ports on this transition. :(
     46 Handle overcurrent conditions.
     47 
     48 Make it possible to open any device in a "generic" way, i.e., like ugen.
     49 Perhaps usbdevfs?
     50 
     51 Rotate the QHs for bulk transport to get fairer scheduling.
     52 
     53 Change HC drivers to queue multiple request for an endpoint
     54 to get better performance.
     55 
     56 Do memory deallocation when HC driver is detached.
     57 
     58 uaudio problems:
     59 	mixer names are awful, use some heuristics.
     60 	implement selector units
     61 	debug input
     62 	test with more devices
     63 
     64 Stylistic changes:
     65 	use usb_ and usbd_ consistently
     66 	rearrange the contents and names of some files (Nick)
     67 
     68 Use splsoftusb() or a thread to deliver callbacks.
     69 
     70 Add threads to the Ethernet drivers.
     71 
     72 Change what's done at watchdog timeout inb if_{a,c,k}ue.c; what we have
     73 now doesn't work because it's done in an interrupt context.
     74 
     75 Factor out the common code from the Ethernet drivers and reuse that.
     76 
     77 Get rid of hcpriv.
     78 
     79 Keyspan serial driver
     80 
     81 Clean up umass driver
     82 
     83 
     84 Documentation:
     85 --------------
     86 
     87 Document device driver API.
     88 
     89 Document HC driver API.
     90 
     91 Update ugen(4)
     92
