we are using ISP1760 along with blackfin processor
Iam writing my own code for enumerating internal hub and external device
First I connected the usb mouse to external port next,I can successfully able to enumerate the internal hub and can power up. The vbus is applied and the mouse is powered up.
The problem is after that sequence i used get port status usb command. I got the value byte0 = 00 byte1 = 01 byte2 = 00 byte3 = 00
From the above it means In portstatus the powered up bit is set and In portchange nothing is set since i connected mouse permanently
but the device connected bit is not set??
The sequence what i follow is correct ? Iam forming the ptd in ATL area itself for getportstatus. Is that okay?
I checked any error bit is set in ptd when i use getportstatus but no Error bit is set.
Can u please help me how to get the device connected status of port1 and enumerating the external device
Please give me some solution
Thanks
