! 3: Some things that need to be done:
! 4: ---------------------------------
! 5:
! 6: High priority:
! 7: --------------
! 8:
! 9: On a short control transfer the status phase needs to be executed anyway.
! 10:
! 11: Allow interrupt out endpoints. (USB 1.1)
! 12:
! 13: Fix flow control in ucom (copy from com driver).
! 14:
! 15: Use some encapsulation in the upl driver to allow multiple protocols.
! 16:
! 17: Get the uezcom driver (with Doug Ambrisko's firmware) running.
! 18:
! 19:
! 20: Bug reports:
! 21: ------------
! 22:
! 23: Bernd Ernesti's problem: host controller halted with umodem
! 24:
! 25: umass problem with Ricoh flash reader
! 26:
! 27: wskbd for X
! 28:
! 29: mel kravitz's problem, lockups with disk and printer
! 30:
! 31: Aaron's problem: Test aue with ohci.
! 32:
! 33:
! 34: General:
! 35: --------
! 36:
! 37: Figure out why uvisor is so slow.
! 38: Try to get specs, and check if Linux driver is really right.
! 39:
! 40: Add lots of bus_dmamap_sync().
! 41:
! 42: Do bandwidth accounting.
! 43:
! 44: Use lock manager locks.
! 45:
! 46: Use the pool allocator for TDs et al.
! 47:
! 48: Throw out more USBDI gunk.
! 49:
! 50: Make hub driver notice transition between self and bus powered state.
! 51: Some hubs change the number of available ports on this transition. :(
! 52: Handle overcurrent conditions.
! 53:
! 54: Make it possible to open any device in a "generic" way, i.e., like ugen.
! 55: Perhaps usbdevfs?
! 56:
! 57: Rotate the QHs for bulk transport to get fairer scheduling.
! 58:
! 59: Change HC drivers to queue multiple request for an endpoint
! 60: to get better performance.
! 61:
! 62: Do memory deallocation when HC driver is detached.
! 63:
! 64: uaudio problems:
! 65: mixer names are awful, use some heuristics.
! 66: implement selector units
! 67: debug input
! 68: test with more devices
! 69:
! 70: Stylistic changes:
! 71: use usb_ and usbd_ consistently
! 72: rearrange the contents and names of some files (Nick)
! 73:
! 74: Use splsoftusb() or a thread to deliver callbacks.
! 75:
! 76: Add threads to the Ethernet drivers.
! 77:
! 78: Change what's done at watchdog timeout inb if_{a,c,k}ue.c; what we have
! 79: now doesn't work because it's done in an interrupt context.
! 80:
! 81: Factor out the common code from the Ethernet drivers and reuse that.
! 82:
! 83: Rewrite HID driver to handle report IDs properly. Perhaps there should
! 84: be a hiddev to which hid with different IDs can attach?
! 85:
! 86: Get rid of hcpriv.
! 87:
! 88: Keyspan serial driver
! 89:
! 90: Clean up umass driver
! 91:
! 92:
! 93: Documentation:
! 94: --------------
! 95:
! 96: Document device driver API.
! 97:
! 98: Document HC driver API.
! 99:
! 100: Update ugen(4)
