Hi,
Finally I solved some problems running WiFi on DaVinci. Some tips
could help run other USB devices.
Tips:
1. Add delay 1 ms in probe function before FW loading.
2. Work on full usb speed, not high. You may use USB 1.1 hub or lower
MGC_M_POWER_HSENAB in MGC_O_HDRC_POWER.
3. Pay attention and fix bulk/interrupt URB types.
4. compile kernel with wireless support or configure driver with
configuration file (for example zd1211.conf, essid=....)
6. restart URB on timeout.
Please see attached patch for ZD1211LnxDrv_2_15_0_0 driver. The
patched driver works on FS, and have problems on HS.
