In host mode it is used for VBUS sensing input. Apart from the low scope bandwidth it looks normal to me. You won’t see sda1 in this case. Or there will be some kind of “protocol plugins”? What’s the scope bandwidth? I have not found any components that seem to be bad. There’s no license included but the readme mentions something about free distribution and modification.

Make sure the probe is clipped to the shortest possible distance between the signal that your monitoring and the nearest ground on the IC.
The ISP is much faster at high speed and support more features.
How configure U-Boot to access USB with ISP1362?
Apart from the low scope bandwidth it looks normal to me. This results in following register mapping unconfirmed: In your image, in one division I see up to 6 periods, which means exactly 12 MHz 83 ns per bit. This is a demo program that comes with a Philips ISP evaluation board. It would be WAY cool if it was ported to Rockbox.

Capture relies on libptp and uses some Canon and Nikon? The scope is set at.
Latest version of this program 1. It’s a DOS program, written with portability in mind and comes with full sources. After compiling the design, the pin assignments must be set. Pin 48 is wrong on the schematic, it is pulled low.
USB driver for Philips ISP
It seems like the iriver uses the first one, because on the US iriver it’s used as device port. The only restriction i isp132 till now is the current with which the chip can supply the usb ports – it’s lower than the standard mA; We will need support for AT LEAST 2 device classes: It looks noisy, that’s it.
Make sure to assign this interrupt sender to the Avalon bus in the next page. A full speed device will have 12Mbps.

If the above method gives errors, or doesnt work with a newer version of quartus, use this file File: What’s the scope bandwidth?
The discussion will be based on iriver H3x0 for the moment, because i have iriver H the other device the RockBox port is working on with USB host caps is IaudioX5but we don’t have the specific chip’s documentation atm.
