u-boot.git/common/usb.c, branch v2018.01 Unnamed repository; edit this file 'description' to name the repository. usb: Read device descriptor after device is addressed for xHCI 2017-10-01T14:32:53+00:00 Bin Meng bmeng.cn@gmail.com 2017-09-18T13:40:43+00:00 932bb668bb2464115f2d08abbed44e58cfce9536 For xHCI it is not possible to read a device descriptor before it has been assigned an address. That's why usb_setup_descriptor() was called with 'do_read' being false. But we really need try to read the device descriptor before starting any real communication with the default control endpoint.

usb: Only get 64 bytes device descriptor for full speed devices 2017-10-01T14:32:53+00:00 Bin Meng bmeng.cn@gmail.com 2017-09-18T13:40:42+00:00 c008faa77358bb5b313696dd1d5bb8afa03a6ca2 Full speed device endpoint 0 can have 8/16/32/64 bMaxPacketSize0. Other speed devices report fixed value per USB spec. So it only makes sense if we send a get device descriptor with 64 bytes to full speed devices. While we are here, update the comment block to be within 80 cols. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 4xx, so remove it. Signed-off-by: Heiko Schocher <hs@denx.de>

usb: move CONFIG_USB_XHCI to Kconfig with renaming 2016-06-03T22:43:53+00:00 Masahiro Yamada yamada.masahiro@socionext.com 2016-06-03T22:35:03+00:00 0a8cc1a3a4206d556da784a0e98598190dfe5408 Move CONFIG_USB_XHCI to defconfig files for all boards, renaming it into CONFIG_USB_XHCI_HCD. As commented in the help of "config USB_XHCI" entry, this has been a TODO for a long time; now CONFIG_USB_XHCI_HCD and CONFIG_USB_XHCI have been unified in favor of the former. Note: Some boards define CONFIG_USB_XHCI in their headers without CONFIG_USB, which does not meet the "depends on" in Kconfig. I added CONFIG_USB=y for those boards when converting. Otherwise, they would fail to build. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
