Official user-processes uses a buffer where the buffer address/size is page-aligned, where '''size''' is the original size before alignment. The user-process also flushes dcache for this buffer using '''size''', before/after using this command. Official sw passes value 0 for '''unk'''. | Official user-processes uses a buffer where the buffer address/size is page-aligned, where '''size''' is the original size before alignment.

Takes 3 input u32s ('''urbCount''', '''unk1''', and '''unk2'''), an input u64 '''buffer''' and u64 '''unk''', and a type-0x5 ([3.0.0+] type-0x21) input buffer, returns an output u32 '''xferId'''. | Takes 3 input u32s ('''urbCount''', '''unk1''', and '''unk2'''), an input u64 '''buffer''' and u64 '''unk''', and a type-0x5 ([3.0.0+] type-0x21) input buffer, returns an output u32 '''xferId'''. | ||

This uses the same func internally as [[#PostBufferAsync_2|#PostBufferAsync]] except multiple urbs are specified by the user: the input buffer contains an array of u32s for the size of each urb, where '''urbCount''' is the total number of entries in this array. With [[#PostBufferAsync_2|#PostBufferAsync]] the last 2 params passed to the internal func are hard-coded to 0, while with this command it's '''unk1''' and '''unk2'''. | This uses the same func internally as [[#PostBufferAsync_2|#PostBufferAsync]] except multiple urbs are specified by the user: the input buffer contains an array of u32s for the size of each urb, where '''urbCount''' is the total number of entries in this array.
