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