      Hi Team,

       

      We are using Cypress 4373 wireless chip on a hardware with usb interface, after compiling the drivers we get compat.ko, cfg80211.ko,brcmutil.ko and brcmfmac.ko modules. After inserting the modules in sequence (compat.ko, cfg80211.ko,brcmutil.ko and brcmfmac.ko) we get error "brcmf_usb_dl_cmd: usb_submit_urb failed -19" after brcmfmac.ko is inserted.

      Please let us know how do we resolve the issue.

       

      Thanks

      Ajit
