Hi,I find the similiar problem in 2.4.22 and it has puzzled me for 3 days. My device is built with PDIUSBD12 and the firmware is dirived from the official demo. The difference is: the first 8 byte transfer success (without 'followed by frames full of OUT and NAKs'), but the followed SET transfer is time-out.
I'm trying to connect a scanner to my embedded linux PXA platform (2.6.0-test2 with Cypress 67300 controller). It appears the device fails to enumerate due to linux only reading 8 bytes during the initial GetDescriptor frame.
The device works properly when connected to a Windoze machine, which does a GetDescriptor prior to SetAddress. This results in the GetDescriptor after SetAddress reading all 18 bytes.
Windows trace: GetDescriptor (Device) h->d setup (ack) h<-d in (ack) h->d out (ack) SetAddress h->d setup (ack) h<-d in (ack) GetDescriptor (Device) h->d setup (ack) h<-d in (ack) h<-d in (ack) h<-d in (ack) h->d out (ack) ..... and everything works.
On linux (both desktop and embedded device) I get
SetAddress h->d setup (ack) h<-d in (ack) GetDescriptor (Device) h->d setup (ack) h<-d in (ack) h->d out (nak) ... followed by frames full of OUT and NAKs
